the radius of a Planet A is half the radius of planet B. If the mass of A is Ma, what must be the mass of B so that the value of g on b is half that of its value on A??... PLZ HELP

g=GM/r^2
G- gravitational constant
r- radius of planet
M- mass of planet
R-radius of planet A
So, radius of planet B=2R
ga=GMa/R^2 ---------eq1
gb=GMb/(2R)^2--------eq2
gb=1/2ga----------eq.3
Put eq.1 and eq. 2 in eq.3
You can then get Mb.
I hope this helps:-)
