Question

A hollow neutral conducting sphere is placed in between two charged plates. Which of the following statement/s is true for the electric field in the sphere?

• A. The strength of the electric field is inversely proportional to the distance from the plates.
• B. The strength of the electric field is uniform.
• C. The strength of the electric field is inversely proportional to the distance from the plates squared.
• D. The strength of the electric field is zero.

Answer 1

Answer: (B), (C)

The correct options are
B The strength of the electric field is uniform.
C The strength of the electric field is inversely proportional to the distance from the plates squared.

A is false because C is correct statement.

B is true because the plates are oppositely charge and close to each other. The field begins at the red plate and ends uniformly at the blue.

C is true because the formula for electric field is given by $E=\frac{q}{4\pi \epsilon r^2},$ where r is the distance.
