Answer #1

Acceleration of a rolling body on an inclined plane of inclination is given by

  where M is mass of body, R is radius of body, I is moment of inertia of body.

For hollow sphere,

For solid sphere,

We can see, acceleration of solid sphere is greater than the acceleration of hollow sphere, therefore, time taken to reach bottom is lesser for solid sphere as compared to hollow sphere.

Solid sphere reaches the bottom first.
