What would happen if gravity suddenly disappears?

Explanation

If gravitational force ceased to exist on earth , then :
(a) All the objects will no longer be drawn towards each other and the earth . Objects not being attracted to the earth along - with humans would float off into space away from the surface of the earth .
(b) The important consituents of the earth uncluding the atmosphere and the water from the ocean, seas etc would also float into space .
(c) The moon would stop orbiting the earth and would drift in space .
