Question

A body weighs 600N on the surface of the earth and 450N on the surface of another planet. Calculate the value of g in that planet (g on the earth = 10 N/Kg)

Answer 1

Weight on Earth = 600N
Weight on Planet = 450N
Weight, W = Mg
M=Wg
Mass of body=^600N/_10N/Kg=60Kg
g=wm
g=^450N/_60Kg=7.5N/Kg
