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

Solution:
During rolling motion, there is radial acceleration towards the centre. Hence, the contact point moves vertically upward.
On smooth surface, sphere will slide without rolling.
