Answer :

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 = MA;


Radius of Planet A = RA;


Value of ‘g’ on A = gA;



Mass of Planet B = MB;


Radius of Planet B = RB;


Value of ‘g’ on B = gB;



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 MB = 2MA .
