a particle is moving in circular path. its motion is uniform a)if the angular velocity is constant and in the same direction. b)if the tangential velocity is constant and in the same direction. c)if it has a uniform acceleration d)if it has no acceleration e)none of these

In uniform circular motion speed of the body is constant but velocity changes continuously due to change in direction. Change in velocity is constant for equal time intervals, so acceleration is constant.
So correct options are a and c.

it will be A only.
just see, direction of acceleration will change with time . so not C.
rate if found useful
nso again, right?

@karan singh
the option c says accelration is uniform not contant
so it is also right
