Weight of 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

If density of earth increased 4 times and its radius becomes half of then out weight will be ......

A man can jump to a height of 1.5 m on a planet A what is the height ne may be able to jump on another planet whose density and radius are respectively one- quater and one- third that of planet A

The acceleration of a body due to the attraction of the earth (radius R) at a distance 2R from the surface of the earth is = ...............
(g = acceleration due to gravity at the surface of earth)

The height at which the weight of a body becomes 1/16 th its weight on the surface of (radius R) is

The tidal waves in the sea are primarily due to

The atmosphere is held to the earth by

Two identical solid copper spheres of radius R are placed in contact with each other. The gravitational attraction between them is proportional to

The gravitational force F_g between two objects does not depend on

Gravitational mass is proportional to gravitational
