A solid sphere  of mass  and radius  and another sphere  of mass  and radius  are simultaneously released at rest from the top of an inclined plane as shown in figure. The spheres roll without slipping. Also we may consider the spheres and the surface on which they roll to be perfectly rigid. Match Columns I and II

Column-I

Column- II

(A)

More for sphere

(p)

Speeds of the two spheres at the bottom of the incline

(B)

More for sphere

(q)

Time taken by the spheres to reach the bottom

(C)

Same for both spheres

(r)

Angular acceleration

(D)

Zero

(s)

Kinetic energy at the bottom

Answer Key / Explanation : (c) -

(c)

Velocity of two sphere will be the same at the bottom

where

So kinetic energy of smaller mass will be more at the bottom

Also and

As , for smaller sphere,  and the larger sphere

Whereas  time will be the same for both the spheres as  will be same
