The acceleration due to gravity (g) on the surface of a planet is given by the formula g = GM/R², where G is the gravitational constant, M is the mass of the planet, and R is its radius.
A planet has a mass M₁ and radius R₁. The value of acceleration due to gravity on its surface is g₁. There is another planet 2, whose mass and radius both are two times that of the first planet. Which one of the following is the acceleration due to gravity on the surface of planet 2?
