Q1PhysicsUnit 6: Gravitation

The height at which the value of acceleration due to gravity becomes

50 \%

of that at the surface of the earth. (radius of the earth

=\mathbf{6 4 0 0 k m}

) is

Q2PhysicsUnit 6: Gravitation

If the mass of the body on the surface of the earth is

50 k g,

its mass at the centre of the earth is:

Q3PhysicsUnit 6: Gravitation

Suppose that the acceleration of a free fall at the surface of a distant planet was found to be equal to that at the surface of the earth. If the diameter of the planet were twice the diameter of the earth, then the ratio of mean density of the planet to that of the earth would be:
