Figure shows a body of mass m moving with a uniform speed v along a circle of radius r . The change in velocity in going from A to B is

A

`vsqrt(2)`

B

`v//sqrt(2)`

C

v

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
A
Change in velocity `(Deltav) = 2v sin (theta/2)`
`= 2v sin (90/2) = (2v)/sqrt(2) = vsqrt(2)`
