Question

How much work is done by the rope to keep a ball of mass 1 kg in uniform circular motion at speed 5 m/s?

Answer 1

Answer #1

Workdone will be zero.

Tension is along the radial direction. And the motion of ball is along the tangential direction.

Force and displacement is perpendicular to each other.

All the best !!
