MCQ

A uniform sphere is placed on a smooth horizontal surface and a horizontal force F is applied on it at a distance h above the surface. The acceleration of the centre:

A
Is maximum when h = 0.
B
Is maximum when h = R.
✓
Is maximum when h = 2R.
D
Is independent of h.

✓

Answer

Correct option: C.

Is maximum when h = 2R.

Explanation:

As the uniform sphere is placed on a smooth surface, the sphere only slips.

The acceleration of the centre of the sphere is given by,

$\frac{\text{Applied force}}{\text{Mass of the sphere}},$ which is independent of height h.
