A thin, metallic spherical shell contains a charge \(\mathrm{Q}\) on it. A point charge \(\mathrm{q}\) is placed at the centre of the shell and another charge \(\mathrm{q}_1\) is placed outside as it is shown in the figure. All the three charges are positive. The force on the charge at the centre is:
         
1. towards left
2. towards right
3. upward
4. zero

Some charge is being given to a conductor. Then it's potential:

1. is maximum at the surface.
2. is maximum at the centre.
3. remains the same throughout the conductor.
4. is maximum somewhere between the surface and the centre.

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.
