Question

when a body performs uniform circular motion, the work done is zero (give scientific reason) ​

Answer 1

Answer:

The only force is the centripetal force, which points in a direction along the radius of the circle, and since the radius of the circle never change, there is no displacement along this direction, and the work done by this force is zero.

Answer 2

when a body performs uniform circular motion the work done is zero as when a body is performing a circular motion in a same or in a uniform speed then the work is zero as it is not equal it is it doesn't equal to to one or two or any other number because when you are performing any activity in a circular manner the force or the work you have put equals to acceleration zero
