If a_r and a_trepresent radial and tangent

Your Ultimate Guide to JEE & NEET Question Solutions

If ${a_r}$ and ${a_t}$represent radial and tangential accelerations, the motion of a particle will be uniformly circular if

${a_r} = 0$ and ${a_t} = 0$

${a_r} = 0$ but ${a_t} \ne 0$

${a_r} \ne 0$ but ${a_t} = 0$

${a_r} \ne 0$ and ${a_t} \ne 0$

If ${a_r}$ and ${a_t}$represent radial and tangential accelerations, the motion of a particle will be uniformly circular if

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