Solve the followi

We know that acceleration due to gravity (g) is given by

Where G = universal gravitational constant;

M = mass of the planet;

R = radius of the planet;

Mass of Planet A = M_A;

Radius of Planet A = R_A;

Value of ‘g’ on A = g_A;

Mass of Planet B = M_B;

Radius of Planet B = R_B;

Value of ‘g’ on B = g_B;

Also it is given that;

Therefore;

(from question )

⇒

Therefore the mass of planet B should be two times the mass of planet A i.e M_B = 2M_A .
