Q. No.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. |
