1) If a planet has a radius 20 % greater than that of the Earth but has the same mass as the Earth , what is the acceleration due to gravity at its surface ? 2) An object of mass 0.50 kg is transported to the surface of Planet X where the object's weight is measured to be 20 N. The radius of the planet is 4.0 x 10^6 m. What free fall acceleration will the 0.50-kg object experience when at the surface of Planet X
