An impulse `J` is applied on a ring of mass `m` along a line passing through its centre `O`. The ring is placed on a rough horizontal surface. The linear velocity of centre of ring once it starts rolling without slipping is

A

`(J)/(m)`

B

`(J)/(2m)`

C

`(J)/(4m)`

D

`(J)/(3m)`

Text Solution

Verified by Experts

The correct Answer is:
A
`E=|Z|l=|4+3j|2=sqrt(4^(2)+3^(2))xx2=10V,phi = "arg " Z = tan^(-1).(3)/(4)=37^(@)`
