in gravitation a force of attaraction acts b/w two bodies having gome mass.
earth can be considered as made up of n particles of mass m. these n masses remain together due to the force of attaraction acting b/w them acc to newton's formula F=Gmm/rr.
and then acc to superposition principle, the vector sum of all the forces is to be considered.so earth is round.
but if the force of gravitation becomes opposing, each partice will move away from every other particle and thus earth shall turn into a mess of discrete particleslying at positions where force by one is calcelled by the other ie null point.
