JEE PYQ: Rotational Motion Question 34

Question 34 - 2020 (06 Sep Shift 2)

The linear mass density of a thin rod AB of length L varies from A to B as $\lambda(x) = \lambda_0\left(1 + \frac{x}{L}\right)$, where $x$ is the distance from A. If $M$ is the mass of the rod then its moment of inertia about an axis passing through A and perpendicular to the rod is:

(1) $\frac{5}{12}ML^2$

(2) $\frac{7}{18}ML^2$

(3) $\frac{2}{5}ML^2$

(4) $\frac{3}{7}ML^2$
