Question

. The value of gravitational acceleration g at the surface of earth is 10 m/s2

. The mass of planet

Mars is one-fifth and radius half of earth. Find the gravitational acceleration at the surface of mars

Answer 1

We know that the acceleration due to gravity is equal to 9.8 m/s2, the Gravitational constant (G) is 6.673 × 10−11 Nm2/kg2, the radius of the Earth is 6.37 × 106 m, and mass cancels out.

Hope this helps.
