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,

Options:

A . m1 : m2

B . r1 : r2

C . 1 : 1

D . m1 r1 : m2r2

Answer: Option B
:
B
Centripetal acceleration,
a =

w^{2}

r =

(\frac{2 π}{T})^{2}

. r

∴

\frac{a_{1}}{a_{2}}

\frac{r_{1}}{r_{2}}
