If the radius of the earth be increased by a factor of `5`, by what factor its density be changed to keep the value of `g` of the same?

If the radius of the Earth were increased by a factor 5, by what factor would its density have to be changed to keep the value of acceleration due to gravity the same?

If the radius of the earth were incresed by a factor of 3, by what factor would its density to be changed to keep 'g' the same ?

Keeping mass unchanged if radius of the earth increases by a factor 4, then by which factor density must have to be changed so that the value of g remains same ?

If the radius of the earth were increased by a factor of 2 keeping the mass constant, by what factor would its density have to be changed to keep g the same?

If the radius of the earth were increased by a factor of 2 keeping the mass constant, by what factor would its density have to be changed to keep g the same?

If the radius of the earth were increased by a factor of 2 keeping the mass constant, by what factors would its density have to be changed to keep g same?

If the radius of the earth becomes half of its present value but its density remains unchanged then find the weight of body on the surface of earth.

If the distance between two bodies is increased by a factor of 5, (i) by what factor will the gravitational force change if the masses are kept consant ? (ii) by what factor will the mass of one of them have to be altered, keeping the other mass the same, to maintain the same gravitational force between the two bodies.?

Answer the following questions : If the distance between two bodies is increased by a factor of 5, By what factor will the gravitational force change if the masses are kept constant?
