Gravitation Tes...

The mass of earth is $$80$$ times that of moon and its diameter is double that of moon. If the value of acceleration due to gravity on earth is $$9.8 m/s^{2}$$, then the value of acceleration due to gravity on moon will be

The gravitational force between two bodies is $$6.67\times 10^{-7}N$$ when the distance between their centres is 10 m. If the mass of first body is 800 kg, then the mass of second body is :

A body of mass $$5\ kg$$ is taken into space. Its mass:

In the Newton's gravitational law, $$F = \dfrac{G M m}{d^{2}} $$, the quantity G:

Two spherical balls each of mass $$1 kg$$ are placed $$1 cm$$ apart. The gravitational force of attraction between them is

The mass of a ball is four times the mass of another ball. When these balls are separated by a distance of $$10cm$$, the gravitational force between them is $$6.67\times 10^{-7}N$$ . The masses of the two balls are

The universal law of gravitation gives the gravitational force between

Moon is revolving in a circular orbit with a uniform velocity $$V_{0}$$. If the gravitational force suddenly disappears, the moon will

If the gravitational force of earth suddenly disappears, then which of the following is correct? 

If suddenly the gravitational force of attraction between earth and satellite revolving around it becomes zero, then the satellite will
