Rotational Motion Question 47
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:
[AIPMT 2002]
Options:
A) $ h=R $
B) $ h=2R $
C) $ h=0 $
D) the acceleration will be same whatever h may be
Show Answer
Answer:
Correct Answer: D
Solution:
- The linear acceleration of centre of mass will be $ a=\frac{F}{m} $ wherever the force is applied.
Hence, the acceleration will be same whatever the value of h maybe.
