The mass of a planet is twice the mass of earth and diameter of the planet is thrie the diameter of the earth, then the acceleration due to gravity on the planet's surface is

The mass of a planet is 4 times the mass of the earth and its radius is 2 times the radius of the earth. The acceleration due to gravity on that planet is

If the mass of a planet is 10% less than that of the earth and the radius is 20% greater than that of the earth, the acceleration due to gravity on the planet will be

If the mass of a planet is 10% less than that of the earth and the radius is 20% greater than that of the earth, the acceleration due to gravity on the planet will be

The acceleration due to gravity on the surface of the earth is 9.8 m*s^(-2) . The size of a planet is the same as that of the earth, but its density is twice the density of the earth. The value of the acceleration due to gravity on that planet is

Solve the following examples / numerical problems: The mass of a planet is 3 times the mass of the earth. Its diameter is 25600 km and the earth's diameter is 12800km. Find the acceleration due to gravity at the surface of the planet. [g (earth)=9.8 m/s^2]

The mass of an imaginary planet is 3 times the mass of the earth. Its diameter 25600 km and the earth's diameter is 12800 km. Find the acceleration due to gravity at the surface of the planet. [g (earth) =9.8m//s^(2) ]
