# Consider two planets A and B. The mass of planet B is 0.012 times the mass of planet A and its radius is 0.3 times the radius of planet A. If the acceleration due to gravity at the planet A is 10 m/s2 , calculate the corresponding value at planet B.

ga = Ma G/Ra^2 gb = [Mb/Ma x (Ra/Rb) ^2] ga gb = [(0.012 * (1/0.3)^2] * 10 = 1.33 m/s^2
