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

Options

A. `a_(f)=0,a_(t)=0`
B. `a_(f)=0,a_(t)ne0`
C. `a_(f)ne0,a_(t)ne0`
D. None of these

Answer

C

Explanation

incircular motion, `a_(r)` can never be zero. So, option (c) is correct.
