If `a_(r)` and `a_(t)` represent radial and tangential accelerations, the motion of a particle will be uniformly circular if

Options

A. `a_(r) = 0 and a_(t)=0`
B. `a_(r) = 0 and a_(t) ne0`
C. `a_(r) ne 0 and a_(t) =0`
D. `a_(r) ne 0 and a_(t) ne0`

Answer

3

Explanation

In uniform circular montion tangential acceleration reamains zero but magnitude of radial acceleration remains constant.
