Assertion : Work done by the centripetal force in moving a body along a circle is always zero.
Reason : Because displacement of the body is along the force.

Work done by centripetal force is zero . (T or F)

What is the work done by centripetal force in moving a body through half of the cycle ?

(A): No work is done by the centripetal force acting on a body moving along the circumference of a circle (R) : At any instant, the motion of the body is along the tangent to the circle whereas the centripetal force is along the radius vector towards the centre of the circle

Work done by a force in displacing a body is an example of

Why is the work done by a centripetal force equal to zero?

Assertion: Work done by the force of friction in moving a body around a closed loop is zero. Reason: Work done does not depend upon the nature of force.

Assertion: Work done by the force of friction in moving a body around a closed loop is zero. Reason: Work done does not depend upon the nature of force.

Assertion : Work done by orforce of friction in moving a body through any round trip is zero. Reason : Because friction is a conservative force.
