To calculate tension in a cable, take the mass of the section of cable and consider the force applied straight downward due to the acceleration of gravity. Divide that by two because the cable is supported at both ends. That is the force applied to one support in a downward direction. Now, consider the angle of the cable relative to vertical at the support. Using simple vector analysis, determine the force in the direction of the cable. That is the tension of the cable.
If you also calculate the horizontal force vector at the support, that would be the force pulling the two supports together, although that is not usually an issue because there is often another section of cable on the opposite side of the support which balances the horizontal force vector.
In many cases you can assume that the tension all along the rope is the same - this ignores the weight of the rope. Use Newton's Second Law to find the force - assuming you know the mass and the acceleration. The mass is basically any mass that the rope is pulling.

What will be the tension in a rope that is pulled from its ends by to opposite forces100 N each?
Assuming you meant two forces, the tension will be 200N.
Where is the tension most if a stone is tied to a rope and rotated in a vertical circular path with uniform motion?
Along the rope. A vector arrow would be applied and point directly inward here in many physics books on mechanics.
When a 100 N bag of nails hangs motionless from a single vertical strand of rope how many newtons of tension are exerted in the strand?
143
When a 10-N object is suspended at rest by two vertical strands of rope the tension in each rope is?
The tension in each rope would be 5 N. This is because the weight of the object (10 N) is divided equally between the two ropes, resulting in each rope supporting half of the weight (5 N) to keep the object suspended at rest.
What are paired forces?
Paired forces are two forces that are equal in magnitude but act in opposite directions on an object. Examples include the force of gravity pulling an object downward and the normal force acting upward to balance it, or the tension in a rope pulling on an object and the equal and opposite tension in the object pulling on the rope.
How do you find tension on the rope?
The tension on a rope can be calculated using Newton's second law, which states that the sum of the forces acting on an object is equal to the mass of the object multiplied by its acceleration. By setting up equations for forces in each direction, one can solve for the tension in the rope.
What is a pulling force in a rope called?
A pulling force in a rope is called tension. Tension is the force exerted by a rope when it is pulled taut by two opposing forces.
How much tension is there in a vertical rope that holds a 20N bag of apples at rest?
The tension at every point in the rope must be 20N, and it must exert 20N of upward vertical force on the top of the bag. If there's any point in the whole arrangement where the upward and downward forces are not exactly equal, then the mass at that point must be accelerating up or down.
What is the reaction force to you pulling on a rope?
The reaction force to you pulling on a rope is the tension force exerted by the rope in the opposite direction. This tension force is equal in magnitude and opposite in direction to the force you apply to the rope.
What will be the tension in a rope that is pulled from its end by two opposite forces 100Newton each?
The tension in the rope will be 100 Newtons. Each force of 100 Newtons will act in opposite directions on the rope, resulting in an equal tension force along the length of the rope.
What is the direction of tension in a rope?
The direction of tension in a rope is away from the object to which the force is being applied. It is a pulling force that stretches the rope and opposes any external forces trying to compress or shorten it.
What will be the tension in a rope that is pulled from its ends by two opposite forces 100 n each?
The tension in the rope will be 100 N, as both forces are pulling on the rope with equal magnitude but in opposite directions. This results in no net force being applied to the rope, maintaining the tension at 100 N.
How much tension is in a vertical rope that holds a 20N bag of apples at rest?
The tension at every point in the rope must be 20N, and it must exert 20N of upward vertical force on the top of the bag. If there's any point in the whole arrangement where the upward and downward forces are not exactly equal, then the mass at that point must be accelerating up or down.
What will be the tension in a rope that is pulled from its ends by to opposite forces100 N each?
Assuming you meant two forces, the tension will be 200N.
Where would you find tension in physics?
In physics, tension is a force that is transmitted through a system, typically through a string, rope, or cable. Tension can be found in scenarios such as a hanging weight on a rope, a tightrope walker balancing, or a suspension bridge supporting its own weight and traffic load.
A 2.0 kg rope hangs from the ceiling What is the tension at the midpoint of the rope?
The tension at the midpoint of the rope is equal to half the weight of the rope, as the rope is in equilibrium. Therefore, the tension would be 2.0 kg * 9.8 m/s^2 / 2 = 9.8 N.
What is the force on a rope?
The force on a rope is typically determined by the tension applied to it. This tension arises from the pulling or stretching of the rope, causing the rope to support a load or resist a force. The force on a rope can be calculated using principles of Newton's laws of motion and equilibrium.
