Question

Answer

Spherical shell ( charged)has no electric field inside, so there is no force acts on a charge inside the shell irrespective of position inside the shell too.

Answer

Explanation:

When a positive charge is placed inside a positively charged spherical shell, the following scenario occurs:

1. Electric Field Inside the Shell:
- According to Gauss's Law, the electric field inside a closed conducting shell is zero if no charge is present within the shell.
- Since the positive charge is placed inside the shell, it does not contribute to the net charge enclosed by the shell.
- Therefore, the electric field inside the shell is zero.

2. Electric Field Outside the Shell:
- The positive charge placed inside the shell creates an electric field outside the shell.
- Since both the charge inside the shell and the shell itself are positively charged, their electric fields will be in the same direction.
- As like charges repel each other, there will be a repulsion between the charge inside the shell and the shell itself.

3. Overall Behavior:
- The charge placed inside the shell experiences a repulsive force from the shell due to the electric field.
- However, the shell itself does not experience any force or motion as it is a stationary object.
- Therefore, the overall behavior of the system is that there is neither attraction nor repulsion between the charge and the shell.

In conclusion:
- When a positive charge is placed inside a positively charged spherical shell, there is no attraction or repulsion between them.
- The charge inside the shell experiences a repulsive force from the shell due to the electric field, but the shell itself remains stationary and does not move.
- Hence, the correct answer is option 'A' - Neither attraction nor repulsion.

Answer

Since there's no electric field inside a positively charged spherical shell so option a become a right answer

Answer

See, it's not possible that putting something inside the shell will not have any effect at all. The underlying concept behind having charge zero inside shell is due to its geometry. It gets cancelled by overall summation of vectors. Similarly when we put a positive charge inside a shell surely the shell will oppose the act initially but down the line it will cancel out due to symmetry and no effect.

Answer

Yes

Answer

Ans.(a), correct because outer charge distribut symmetrical so net force on positive charge is zero
