A man on earth can jump to a maximum height of 2m. To what maximum height.the man will be able to jump to another planet whose density is `1/3`of the density of earth and radius is `1/4`of the radius of earth?

What is the relation between average density and radius of the earth ?

A man can jump up to a height of 1.5 m on the earth's surface. What should be the radius of a planet having the same average density as that of the earth so that the man can come out of the gravitational field of that planet in one jump ? Radius of the earth is 6400 km.

At what height above the surface of the earth will the acceleration due to gravity be one-fourth of its value on the surface of the earth ?[Radius of the earth =R]

What will be the gain in the potential energy of an object of mass m raised from the surface of the earth to a height equal to the radius R of the earth ?

A body weight 63 N on the surface of the earth. What is the gravitational force on it due to the earth at a height equal to half the radius of earth ?

The value of the escape velocity from the earth is v_e . If the radius of a planet is 4 times that of the earth and its density is 9 times the density of the earth, then the value of the escape velocity from that 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

A body weight 90 kgf on the surface of earth. How much will it weight on the surface of a planet whose mass is 1/9 and radius 1/2 that of the earth ?
