Question

Assertion:- Work done in moving a body in uniform circular motion is non-zero.
Reason:- The centripetal force always acts along the radius of the circle.

a) Both, Assertion and Reason are true and Reason is the correct explanation of
Assertion.
b) Both, Assertion and Reason are true but Reason is not the correct
explanation of the Assertion.
c) Assertion is true but the Reason is false.
d) Assertion is false and Reason is true.

Answer 1

Answer:

option C

Explanation:

Work done by centripetal force is zero, because displacement of body is perpendicular to the direction of force, W=Fscos90∘=zero

Answer 2

Answer:

c) Assertion is true but the Reason is false.
