Question

The figure shows a rectangular wire $ABCD$. About which axes the moment of inertia of the wire will be minimum? (Given: $BC=2AB$)

• A. $BC$
• B. $BD$
• C. $HF$
• D. $EG$

Answer 1

The correct option is D $EG$

moment of inertia of a particle located at distance d from a axis= $m{d}^2$
by using the above logic.
The moment of inertia about EG is minimum because the particles are located lesser distance than that of other axis .
