A wheel is rotating with angular velocity 2 rad/s. It is subjected to a uniform angular acceleration 2 rad/s2 then the angular velocity after 10s is

A

12 rad/s

B

20 rad/s

C

22 rad/s

D

120 rad/s

Text Solution

Verified by Experts

The correct Answer is:
C
`omega= omega_(0)+alphat`
Here `omega_(0)=2 "rad"//s^(2) t=10s`
`omega=2+2xx10=22 "rad"//s`
