Q. In case of circular motion of a body, if tangential force also acts on the body in addition to centripetal force, then work done:
Work, Energy and Power
A
by both the forces is zero
23%
B
by both the forces is positive
21%
C
by centripetal force is zero but work done by tangential force is not zero
34%
D
by tangential force is zero by work done by centripetal force is not zero
22%
Solution:
In circular motion centripetal force is always perpendicular to instantaneous displacement, whereas tangential force is along the displacement.
