A solid sphere rolling on a rough horizontal surface. Acceleration of contact point is zero.
A solid sphere can roll on the smooth surface.

A

Statement I is True, Statement II is True, Statement ll is a correct explanation for Statement I.

B

Statement I is True, Statement II is True, Statement II is NOT a correct explanation for Statement I

C

Statement I is True, Statement II is False.

D

Statement I is False, Statement II is True.

Text Solution

Verified by Experts

The correct Answer is:
D

During the motion of rolling there is radial acceleration towards the centre. Hence the contact point moves vertically upwards.
