A particle is performing uniform circular motion with velocity `40m//s`. If the angle between the two velocity vector is `60^(@)`, then the change in velocity will be

A

`30m//s`

B

`40m//s`

C

`20m//s`

D

`10m//s`

Text Solution

Verified by Experts

The correct Answer is:
B
`Deltav = 2v sin (theta/2)=2xx40 sin 30 `
`=80 sin 30 =80 xx(1)/(2)=40m//s`
