A student of weight 830 N was sent to another planet called Nerdland. If Nerdland has a mass that is three times the mass of the earth and a radius that is half the radius of the earth, what would be the mass in kg of the student when on Nerdland?
The change in Wt. that you experience when on a different planet is not caused by a change in your mass. Your
mass is constant. The change in wt. is
caused by the change in gravity(g).
