Imagine a new planet having the same density as that of earth but 3 times bigger than the earth in size. If the acceleration due to gravity on the surface of earth is g and that on the new plane is g , then :

Let g be the acceleration due to gravity on the earth's surface.

If g is the acceleration due to gravity on the surface of the earth , its value at a height equal to double the radius of the earth is

If g is acceleration due to gravity at the surface of the earth, then its value at a depth of 1/4 of the radius of the earth is

If R is the radius of the earth and g the acceleration due to gravity on the earth’s surface, the mean density of the earth is

If R is the radius of the earth and g the acceleration due to gravity on the earth's surface, the mean density of the earth is

If the density of the planet is double that of the earth and the radius 1.5 times that of the earth, the acceleration due to gravity on the planet is

Define acceleration due to gravity. Derive expression of 'g' from the surface of the earth.
