Question

Define balanced forces and unbalanced force.
State whether balanced or unbalanced force acts on a body when it is at rest.

Answer 1

If the net force on a body is zero, it is said to be subjected to a balanced force. If there are two forces then it must be equal in magnitude and oppsite in direction to make a balanced force.

If net force on a body is non-zero, it is said to be subjected to an unbalanced force.

When a body stays at rest, a balanced force is acting on it.
