Assuming the mass of Earth to be ten times the mass of Mars, its radius to be twice the radius of Mars and the acceleration due to gravity on the surface of Earth is 10 m / s 2 . Then the acceleration due to gravity on the surface of Mars is given by

Question

Assuming the mass of Earth to be ten times the mass of Mars, its radius to be twice the radius of Mars and the acceleration due to gravity on the surface of Earth is 10 m / s 2 . Then the acceleration due to gravity on the surface of Mars is given by, 0 . 4 m s - 2, 2 m s - 2, 4 m s - 2, 5 m s - 2

MARKS App · Accepted Answer

Given, mass of earth = 10 × M m Where, M m = Mass of mars Radius of earth = 2 R m Where, R m = radius of mars And g = G M R 2 Let gravity on the surface of mass is g m ∴ g m g E = M m M E × R E R m 2 g m = g e × M m M E R E R m 2 = 10 × M m 10 M m 2 R m R m 2 = 4 m / s 2
