Q.
Moment of inertia of a sphere of mass $M$ and radius $R$ is $I$. Keeping $M$ constant if a graph is plotted between $I$ and $R$, then its form would be
A)
B)
C)
D)
Explanation
(d) $I = \frac{2}{5}MR^{2}\ \therefore I \propto R^{2}$
This relation shows that graph between $I$ and $R$ will be parabola symmetric to $I$-axis
