Question

Assertion: Linear momentum of a body changes even when it is moving uniformly
in a circle.
Reason: In uniform circular motion velocity remain constant.
Both assertion and reason are true and the reason is the correct explanation of
the assertion.
Both assertion and reason are true but reason is not the correct explanation of
the assertion.
Assertion is true but reason is false.
The assertion and reason both are false.​

Answer 1

Answer:

In a circular motion, even though thespeed remains a constant, the direction of velocity (which is tangential to the point on a circle) ischanging throughout the motion as shown: ... Being linear momentum a vector quantity, it's value is completely described by specifying both magnitude and direction
