There is a crater of depth 
on the surface of the moon, where R is the radius of the moon. A ball is projected vertically upwards from the crater with a velocity which is equal to the escape velocity from the surface of the moon. If the maximum height attained by the particle is close to nR, where n is an integer, then find the value of n?
