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. |
