From a uniform sphere of radius ‘R’ a spherical cavity of radius  $\frac{R}{2}$ is removed from the edge as shown. The mass of the sphere after removing cavity is  $M_0$. Consider points A, B, C, D. Assume potential at infinity is zero. ‘C’ is the centre of the cavity and AB = R

	Column – I		Column – II
A)	The gravitational field at A is ‘g’. Then  $\frac{g{R}^2}{G{M}_0}$ is	(P)	$\frac{8}{7}$
B)	The gravitational potential at B is V. Then  $-\frac{VR}{G{M}_0}$ is	(Q)	$\frac{4}{7}$
C)	The gravitational potential at C is V. Then  $-\frac{VR}{G{M}_0}$ is	(R)	$\frac{68}{63}$
D)	The gravitational field at D is ‘g’. Then  $\frac{g{R}^2}{G{M}_0}$  is	(S)	$\frac{10}{7}$
		T)	Zero
