Question

When the following bodies having same radius starts rolling down on same inclined plane, identify the increasing order of their accelerations:
I) Hollow cylinder
II) Solid cylinder
III) Solid sphere
IV) Hollow sphere

• A. I, IV, III, II
• B. IV, I, II, III
• C. I, IV, II, III
• D. IV,I, III, II

Answer 1

Answer: (C)

I, IV, II, III

$a=\frac{gsin\theta }{1+\frac{I}{m{R}^2}}$
$I_I>I_{IV}>I_{II}>I_{III}$
$a_I<a_{IV}<a_{II}<a_{III}$
