Gravitation Tes...

If the mass of earth is 80 times of that of a planet and diameter is double that of planet and \'g\' on earth is 9.8 m/s², then the value of \'g\' on that planet is

At what distance from the centre of the earth, the value of acceleration due to gravity g will be half that on the surface (R = radius of earth)

A man can jump to a height of 1.5 m on a planet A. What is the height he may be able to jump on another planet whose density and radius are, respectively, one-quarter and one-third that of planet A

Weight of a body is maximum at

The acceleration due to gravity is g at a point distant r from the centre of earth of radius R. If r

The density of a newly discovered planet is twice that of earth. The acceleration due to gravity at the surface of the planet is equal to that at the surface of the earth. If the radius of the earth is R, the radius of the planet would be

If the density of the earth is doubled keeping its radius constant then acceleration due to gravity will be (g = 9.8 m/s²)

If the value of \'g\' acceleration due to gravity, at earth surface is 10 m/s², its value in m/s² at the centre of theearth, which is assumed to be a sphere of radius R metre and uniform mass density is

Acceleration due to gravity on moon is 1/6 of the acceleration due to gravity on earth. If the ratio of densities of earth (ρ_e ) and moon (ρ_m) is (ρ_e / ρ_m) = 5/3 then radius of moon R_m in terms of R_e will be

Weight of a body of mass m decreases by 1% when it is raised to height h above the earth\'s surface. If the body is taken to a depth h in a mine, change in its weight is
