Page 22 - Force 10

Here is solution of your problem.

Larger the mass greater is the force of attraction and vice

versa,

Two stone ,whatever the sizes ,are smaller in comparison to

the huge mass of the earth. The force of attraction between

two stones is very feeble( small) such that no pulling effect

is observed in front of pulling gravity of the earth.

However if one stone goes to the size of the moon and

another stays very small then we can see the larger stone

pulling the smaller one.

Similarly if there are two huge masses to the sizes of the

Earth or moon or other huge heavenly bodies the force of

gravitation between them would be very large.

That is the reason why Moon revolves round the Earth and

Earth revolves round the Sun.
