Question

Two cars of masses $m_1$ and $m_2$ are moving in circles of radii $r_1$ and $r_2$, respectively. Their speeds are such that they make complete circles in the same time $t$. The ratio of their centripetal acceleration is

Professor PC Thomas Classes · Answer

(b) : Centripetal acceleration, $a_c=\omega^2 r \quad \because \quad \omega=\frac{2 \pi}{T}$ As $\quad T_1=T_2 \quad 	herefore \quad \omega_1=\omega_2 \quad 	herefore \frac{a_{c_1}}{a_{c_2}}=\frac{r_1}{r_2}$
