Solution :
Distance between the Earth and the moon, D =

Radius of the earth, r =

Gravitational force on the near side of the moon,
......(1)
Gravitational force on the far side of the moon,
..............(2)
where,
= mass of moon
m = mass of the near side and far side respectively (both are taken as equal)
Therefore,




= 7%
Hence, correct option is (b) About 7% greater
