What causes a pithball to move in an experiment involving a pithball electroscope?
A pithball moves in response to the electrostatic force between the charged object and the pithball. When a charged object is brought close to the pithball, the charges on the object induce a separation of charges in the pithball causing it to become attracted or repelled, leading to its movement.
electrons jump onto or off the neutral ball when a charge object comes close to it,causing it to become charged.
Electrical fields, analogous to magnetic fields around magnets.

What if the electroscope leaves hang down?
If the leaves of an electroscope hang down, it typically indicates that the electroscope is positively charged since like charges repel each other. The excess positive charge on the electroscope causes the leaves to spread apart due to the repulsive force.
How can you test for the presence of a charge?
One way to test for the presence of a charge is by using an electroscope. When a charged object is brought near the electroscope, it causes the leaves to diverge due to the interaction of the charges present. Another method is by using a charge sensor, such as a metal ball attached to a string, which will be attracted or repelled depending on the presence of charge.
What causes the bubble increase in yeast fermentation experiment?
why is it reasonable that, of the three sugars, glucose would result in the most activiity suring the fermentation experiment
What are the 4 most common causes of fires involving electricity?
The most common causes of fires involving electricity are faulty wiring, overloaded circuits, damaged electrical cords, and improperly maintained electrical systems. These issues can lead to overheating and sparking, which can ignite fires.
What are the differences between independent and dependent variables?
Independent variables are controlled or manipulated by the researcher to determine their effect on the dependent variable. Dependent variables, on the other hand, are the outcome or response that is measured in an experiment. The independent variable causes a change in the dependent variable.
In wxperiments involving a pithball electroscope what causes the pithball to move?
The movement of the pithball in a pithball electroscope is caused by the presence of electric charge. Like charges repel each other, so if the pithball becomes charged either positively or negatively, it will move away from a similarly charged object.
In experiments involving a pinball electroscope what causes the pithball to move?
The movement of the pithball in a pinball electroscope is caused by the buildup of static charge on the object being tested. When an object with a charge is brought near the electroscope, it induces a charge on the pithball causing it to move due to electrostatic forces.
What can an electroscope determine?
An electroscope can determine the presence of electric charges. When a charged object is brought close to the electroscope, it causes the leaves of the electroscope to either repel or attract each other, indicating the presence and type of charge.
How do electrons move in an electroscope?
When a charged object is brought close to an electroscope, the electrons in the metal rod of the electroscope are repelled by the like charge on the object. This causes the electrons to move to the leaves of the electroscope, causing them to repel each other and spread apart, indicating the presence of a charge.
How do you charge an electroscope?
by induction
What if the electroscope leaves hang down?
If the leaves of an electroscope hang down, it typically indicates that the electroscope is positively charged since like charges repel each other. The excess positive charge on the electroscope causes the leaves to spread apart due to the repulsive force.
An electroscope has been charged by induction with the help of a charged glass rod the charge on the electroscope will be?
The electroscope will acquire a charge that is opposite in sign to that of the charged glass rod. This is because during induction, the charge separation in the electroscope causes an attraction of opposite charges. The electroscope will acquire the same magnitude of charge as the glass rod, but with an opposite sign.
Why a changed electroscope will discharge when placed near a radioactive material?
A changed electroscope will discharge near a radioactive material because the radioactive material emits ionizing radiation (such as alpha and beta particles) that can ionize air molecules around the electroscope. This ionization causes the charge on the electroscope to leak away, resulting in discharge.
If the leaves of and electroscope spread apart it indicates that?
the electroscope has acquired a net charge. This charge can be positive or negative, depending on the nature of the object that interacted with the electroscope. The repulsion between the like charges on the leaves causes them to spread apart, indicating the presence of a charge.
What is a pithball?
A pith ball is a small, lightweight ball made of a lightweight wood called pith. It is commonly used in physics experiments to demonstrate principles of static electricity. When charged, pith balls can be used to show electrical forces and interactions.
Why does the leaves of an electroscope collapse when you touch the upper part with your hands?
When you touch the upper part of an electroscope with your hands, charge is transferred from your body to the electroscope, neutralizing the charge on the leaves. This causes the repulsive force between the like charges on the leaves to decrease, allowing the leaves to collapse.
Why leaves move closer together if the rod has the opposite charge to the electroscope?
When a charged rod is brought near an electroscope with the opposite charge, the positive and negative charges in the electroscope are attracted to the rod. This causes the leaves to come closer together as the negative charges in the leaves are attracted to the positively charged rod. This movement indicates that the electroscope has detected a charge.
