Q. 7

The density of a rod gradually decreases from one end to the other. It is pivoted at an end so that it can move about a vertical axis through the pivot. A horizontal force F is applied on the free end in a direction perpendicular to the rod. The quantities, that do not depend on which end of the rod is pivoted, areA. angular accelerationB. angular velocity when the rod completes one rotationC. angular momentum when the rod completes one rotationD. torque of the applied force

We know, torque is given by

Where

f= force

l = distance from the center of the axis of rotation.

Hence, only torque will not have any effect of which end of the rod is pivoted.
