The electrostatic potential on the surface of a charged conducting sphere is $$100~\text{V}$$. Two statements are made in this regard.

 Statement I: At any point inside the sphere, electric intensity is zero. Statement II: At any point inside the sphere, the electrostatic potential is $$100~\text{V}$$.

Which of the following is a correct statement?

 1 Statement I is true but Statement II is false. 2 Both Statement I and Statement II are false. 3 Statement I is true, Statement II is also true and Statement I is the cause of Statement II. 4 Statement I is true, Statement II is also true but the statements are independent.
