The top plate of a charged plane capacitor is fixed, whereas the bottom one is kept in equilibrium by the gravitational and electrostatic forces.

If F_g and F_e are gravitational and electrostatic forces between two electrons at a distance 0.1m then F_g//F_e is in the order of

F_(g) and F_(e) represent gravitational and electrostatic force respectively between electrons situated at a distance 10 cm. The ratio of F_(g)//F_(e) is of the order of

Two particles , each of mass m and carrying charge Q , are separated by some distance. If they are in equilibrium under mutual gravitational and electrostatic force then Q//m (in C//kg) is of the order of
