# 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 center. The acceleration of the center of mass of the sphere

(a) is maximum when $h=0$

(b) is maximum when $h=R$

(c) is maximum when $h=\large\frac{R}{2}$

(d) is independent of $h$

$F= ma_{cm}$
The acceleration of the center mass of the sphere is independent of $h$
