Question

The work done by a centripetal force
a) Increases by decreasing the radius of the circle
b) Decreases by increasing the radius of the circle
c) Increases by increasing the mass of the body
d) Is always zero​

Answer 1

Answer:

As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle. ... Thus, the work done by the centripetal force in the case of uniform circular motion is 0 Joules.

Answer 2

maybe I think so it's option a) increasing by decreasing the radius of the circle
