On the surface of earth, the gravitational field is ${\mathrm{E}}_{\mathrm{g}}$ and gravitational potential is V(R = radius of earth).

	Column-I		Column-II
i.	At a height h = R, value of ${\mathrm{E}}_{\mathrm{g}}$	p.	decreases by a factor $\frac{1}{4}$
ii.	At a depth d = $\frac{\mathrm{R}}{2}, \mathrm{value} \mathrm{of} {\mathrm{E}}_{\mathrm{g}}$	q.	decreases by a factor $\frac{1}{2}$
iii.	At a height h = R, value of V	r.	increases by a factor $\frac{11}{8}$
iv.	At a depth d = $\frac{\mathrm{R}}{2},$ value of V	s.	increases by a factor 2
		t.	decreases by a factor $\frac{11}{8}$
