Asked by fathima12 | 11th Nov, 2009, 09:28: PM

Expert Answer:

g = G M / R2

here, g = acceleration due to gravity, G = gravitational constant, M= mass of earth , R = radius of earth.

Given,Mass of planet Mp= 3 M , its radius, Rp = 3 R

then, accn due to gravity, gp = G ( 3 M) / (3 R)2 = G M / 3 R2
