Answer 2

Force Holding a Body on a String

The force that holds a body suspended on a string is known as the tension force. This force is exerted by the string and acts in the direction of the string, preventing the body from falling.

Tension Force: The tension force, denoted as T, is the force transmitted through a string, rope, cable, or similar object when it is pulled tight by forces acting from opposite ends. In the case of a body suspended on a string, the tension force acts upward, counteracting the force of gravity pulling the body downward.

The magnitude of the tension force can be calculated using the formula T = mg, where m is the mass of the object and g is the acceleration due to gravity. This formula indicates that the tension force is directly proportional to the mass of the object.

Therefore, the tension force is what prevents the body from falling when it is suspended on a string.
