What path will the moon take when the gravitational interaction between the moon and earth disappears? `(AS_(2))`

Due to cosmic shower same amount of cations +q are stored in the atmosphere of the earth and the moon. If the gravitational attraction between the earth and the moon is exactly equal to the electric repulsion between them. Then find the value of charge q stored in their atmosphere.

What is the relation between the mean density of the earth and G ?

The force of gravitation between two spherical masses M and m, placed in air, is F . The space between the two spheres is filled with a liquid of relative density 3. What will be the change in the value of the gravitational force acting between the spheres ?

The distance the sun and the earth is 1.5xx10^8 km . At what point on the line joining them, will the gravitational attraction of the sun and that of the earth be equal but opposite ? ( Mass of the sun is 336400 times the mass of the earth )

At what velocity will a rocket escape the gravitational pull of the earth ?

Find expressions for the potential energy (V) and the kinetic energy (K) of the moon in the gravitational field of the earth. Hence find the total energy of the moon and state the significance of its negative sign.

Does the value of escape veloity is same at moon and earth?

What is the difference between gravity and gravitation?

What is the relation between path difference and phase difference?
