Two heavy particles having masses ` m_(1) & m_(2)` are situated in a plane perpendicular to line AB at a distance of `r_(1) and r_(2)` respectively .
What is the moment of inertia of the stystem about axis AB ?

Explanation

Moment of inertia of particle on left is ` I _(1) = m_(1) r_(1)^(2)` .
Moment of Inertia of particle on right is ` I_(2) = m_(2) r_(2) ^(2)` .
Moment of Inertia of the system about AB is `I = I_(1) + I_(2) = m_(1) r_(1)^(2) + m_(2)r_(2)^(2) `
