Moment of inertia of big drop in

I

. If 8 droplets are formed from big drop, then moment of inertia of small droplet is

View answer and explanation

Correct option: A

\frac{I}{{32}}

Option A (

\frac{I}{{32}}

) is correct because the moment of inertia of a sphere is proportional to

mr^2

, and when a big drop splits into 8 smaller drops, the mass of each small drop is

m/8

and the radius is

r/2

.
