JEE PYQ: Rotational Motion Question 13
Question 13 - 2021 (24 Feb Shift 1)
Moment of inertia (M.I.) of four bodies, having same mass and radius, are reported as -
$I_1$ = M.I. of thin circular ring about its diameter,
$I_2$ = M.I. of circular disc about an axis perpendicular to disc and going through the centre,
$I_3$ = M.I. of solid cylinder about its axis and
$I_4$ = M.I. of solid sphere about its diameter.
Then:
(1) $I_1 = I_2 = I_3 < I_4$
(2) $I_1 + I_2 = I_3 + \frac{5}{2}I_4$
(3) $I_1 + I_3 < I_2 + I_4$
(4) $I_1 = I_2 = I_3 > I_4$
