If the flux entering and leaving the enclosed surface respectively are \(\Phi_1\) and \(\Phi_2\) then the electric charge inside the surface is :
- A \(\frac{(\Phi_1 + \Phi_2)}{\epsilon_0}\)
- B \(\frac{(\Phi_1 - \Phi_2)}{\epsilon_0}\)
- C \((\Phi_1 + \Phi_2)\epsilon_0\)
- D \((\Phi_2 - \Phi_1)\epsilon_0\)
Answer & Solution
Correct Answer
(D) \((\Phi_2 - \Phi_1)\epsilon_0\)
Step-by-step Solution
Detailed explanation
\(Q = \epsilon_0 (\Phi_{leaving} - \Phi_{entering}) = \epsilon_0 (\Phi_2 - \Phi_1)\)
