In non-uniform circular motion, the ratio of tangential to radial acceleration is ( $r$ is radius of circle, $v$ is speed of the particle, $\alpha$ is angular acceleration)
  1. $\frac{\alpha r^2}{v^2}$
  2. $\frac{\alpha^2 r}{v^2}$
  3. $\frac{\alpha^2 r^2}{v}$
  4. $\frac{v^2}{r^2 \alpha}$

Solution

Ratio of tangential to radial acceleration is given by, $\frac{a_t}{a_r}=\frac{r \alpha}{v^2 / r}=\frac{r^2 \alpha}{v^2}$
