Why electric intensity at any point inside a charged conductor is zero?

Answer the following :- You can shield a charge from electrical forces by putting it inside a hollow conductor. Can you shield a body from the gravitational influence of nearby matter by putting it inside a hollow sphere or by some other means ?

The electrostatic potential on the surface of a charged conducting sphere is 100 V. Two statements are made in this regard: S_1 : At any point inside the sphere, electric intensity is zero. S_2 : At any point inside the sphere, the electrostatic potential is 100 V. Which of the following is a correct statement?

A point charge +Q is placed at the centre O of an uncharged hollow spherical conductor of inner radius 'a' and outer radius 'b'. Find the following: The magnitude and sign of the charge induced on the inner and outer surface of the conducting shell.
