Two charged conducting spheres of radii 5 cm and 10 cm have equal surface charge densities. If the electric field on the surface of the smaller sphere is E, then the electric field on the surface of the larger sphere is
- A \(2 E\)
- B \(4 E\)
- C \(0.5 E\)
- D \(E\)
Answer & Solution
Correct Answer
(D) \(E\)
Step-by-step Solution
Detailed explanation
\(E = \frac{\sigma}{\epsilon_0}\) Given \(\sigma_1 = \sigma_2\) \(E_1 = \frac{\sigma_1}{\epsilon_0} = E\) \(E_2 = \frac{\sigma_2}{\epsilon_0} = \frac{\sigma_1}{\epsilon_0} = E\)
