Rotational Motion Question 164
Question: A solid sphere of radius R is placed on a smooth horizontal surface. A horizontal force F is applied at height h from the lowest point. For the maximum acceleration of the centre of mass,
Options:
A) $h=R$
B) $h=2R$
C) $h=0$
D) The acceleration will be same whatever h maybe
Show Answer
Answer:
Correct Answer: D
Solution:
[d] As friction is absent at the point of contact,
Force Acceleration $=\frac{Force}{Mass}$
It is independent of h.
