Question

all the planets are moving in circular orbits. what will happen if this force disappears suddenly?

Answer 1

The force which is being talked about is the force of gravity of the sun

If the force disappears the planets will move away from the orbits and will not move in circular motion....

Hope it helps..

Answer 2

All the planets are moving in circular orbits due to some force exerted on them. If this force disappears suddenly then the planets will not be able to move in a circular orbit, the planets will move here and there in the whole universe and they may collide with each other which results in furthur destruction. Due to which our solar system will get devastated.

Hope helps^_^
