Figure shows triangular lamina which can rotate about different axes. Moment of inertia is maximum, about the axis

Options

Correct answer

C. QR

Step-by-step solution

The moment of inertia is given by I = m _ i r _ i ^2 If the distance of particles from the axis of rotation is larger, then the moment of inertia will be larger. For axis QR , the particles will be situated at greater distances and hence the moment of inertia will be greater.
