A thin, metallic spherical shell contains a charge QQ on it. A point charge qq is placed at the centre of the shell and another charge q1q1 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

The electrostatic potential on the surface of a charged conducting sphere is 100 V100 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 V100 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.
