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

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

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

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

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

Solution

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

Two particles, one at the centre of a circle of radius $R$, and another at a point $Q$ on the circle, start moving towards a point $P$ on the circle at the same time (see figure below). Both are at rest initially and move with uniform velocities $\vec{V}_1$ and $\overrightarrow{V_2}$ respectively. They also reach the point $P$ at the same time, If the angle between the velocities is $\theta$ and the angle subtended by $P$ and $Q$ at the centre is $\phi$ (as shown in the figure), then
