Question

work done by centripetalforce is
Zero
positive
Negative
Non of these​

Answer 1

Answer:

zero is answer of your question because angle between force and velocity is 90°

Answer 2

Answer:

Since, the particle always moves in a direction perpendicular to the radial direction in circular motion. Therefore, the dot product is always zero and hence, the work done by centripetal force in a circular motion is always zero
