Question

Consider two masses $m_{1}$ and $m_{2}$ are moving in circles of radii $r_{1}$ and $r_{2}$ respectively. Their speeds are such that they complete circular motion in the same time t. The ratio of their untripetal acceleration is,

$m_{1}$ : $m_{2}$

Solution

The correct option is B
$r_{1}$ : $r_{2}$

Centripetal acceleration,

a = $w^{2}$ r = $(\frac{2 π}{T})^{2}$ . r

$∴$ $\frac{a_{1}}{a_{2}}$ = $\frac{r_{1}}{r_{2}}$
