Question

The direction of rotation of a pivoted body can be changed by changing ______.

विकल्प

• the direction of force.

• the point of application of force.

• both the direction of force and the point of application of force.

• the magnitude of force.

Answer 1

The direction of rotation of a pivoted body can be changed by changing both the direction of force and the point of application of force.

Explanation:

The direction of rotation of a pivoted body depends on the direction of the applied force and its point of application. Changing either of these can reverse the turning effect of the force. Thus, the body may rotate clockwise or anticlockwise.
