The weight of a body is different on different planets.

Text Solution

Verified by Experts

(1) The weight of a body of mass m on the surface of a planet of mass Mand radius R is given by `W=(GmM)/(R^(2))` ( in the usual notation).
(2) For a given body, its mass is constant and G is the universal constant of gravitation. Different planets have different masses and radii such that the ratio `(M//R^(2))` is not the same. Hence, the weight of a body is different on different planets.
