Question Physics: Electrostatic Force and GravitationalForce
A small piece of paper weighs 10ˆ-2 gm. The weight of earth is10ˆ24 kg. The glass rod with a net charge of 10-6C is brought nearthe paper which gets stuck to the glass rod and one can lift thestuck paper against the gravitational pull of the earth. Comparethe force due to gravity on piece of paper and electrostatic forcebetween paper and glass rod.
