A couple.
If they are not coplanar, you would need at least four forces to get a net force (resultant force) of zero.
An object in equilibrium has a resultant force of zero. This means that the forces acting on the object are balanced and there is no acceleration in any direction.
The resultant magnetic moment is dependent on the orientation in which the identical magnets were joined. If they are joined in opposite direction, the net magnetic moment will go to zero.
A couple: 2 parallel forces equal in magnitude, but opposite in direction separated by a distance.
When there are balanced forces acting on an object, the resultant force is zero. This means that the forces are equal in magnitude and opposite in direction, resulting in no acceleration of the object.
Yes if you put them "head to tail" and the head of the fourth one points to the tail of the first one the resultant is zero.
When the resultant force is not zero, it produces an acceleration in the direction of the force according to Newton's second law of motion. This acceleration changes the velocity of an object, causing it to either speed up or slow down depending on the direction of the force.
If the resultant force is zero, it means that the forces acting on an object are balanced. This typically results in the object staying at rest or moving at a constant velocity, according to Newton's First Law of Motion.
a resultant vector not only the resultant of two or three vector. it is the resultant direction of two or many vectors.(let us push an object with same force in opposite direction the resultant is zero and if we push in same direction the force will double.if we pull a object with same force in x and y direction the resultant force in 45 degrees to x axis)
It is certain that two vectors of different magnitudes cannot yield a zero resultant force.
0. An object in equilibrium has constant velocity, which makes its acceleration 0. Since net force=mass times acceleration, this would make the net force zero. Note that there could be multiple forces acting on the object, but since it is in equilibrium they would have to be equal and opposite in direction, to cancel all of the forces out. This would make the net force zero.
