If the acceleration due to gravity on the surface of the Earth is 9.8m//s^2 ,What will be the acceleration due to ravity on the surface of the planet whose mass and radius both are two times the corresponding quantites for the Earth

The work done to raise a mass m from the surface of the earth to a height h, which is equal to the radius of the earth, is :

What will be the acceleration due to gravity on the surface of a planet if its radius is approximately (1/8)^(th) the radius of the earth and its mass is about (1/60)^(th) the mass of earth ?
