A wheel rotates about an axis passing through the center and perpendicular to the plane with slowly increasing angular speed. Then it has
A
tangential velocity and radial acceleration
B
radial velocity and radial acceleration
C
tangential velocity and tangential and radial accelerations
D
Tangential velocity and tangential acceleration
Text Solution
Verified by Experts
The correct Answer is:
C
AS the angular speed of the wheel is slowly increased , it has an angular acceleration `alpha ` and tangential acceleration ` a_(T ) = gamma alpha .` Similarly it has a radial acceleration `a_(R ) .` Thus it has `v_(T ) , a_(T ) and a_(R )`.
