Electric Flux: Practice Problem & Solution

Two surfaces S1 & S2 are shown in figure. when a pt charge is placed at pt P Flux associated with S1 is Φ1 & S2 is Φ2. Which is correct. Electric Flux diagram: Two surfaces S1 & S2 are shown in
\[\phi_{1}>\phi_{2}\]
\[\phi_{1}<\phi_{2}\]
\[\phi_{1}=\phi_{2}\]
can't say any thing

Solution Explained:

To solve this problem, we apply the core principles of Electric Flux. Understanding the underlying formula is key to arriving at the correct answer below:

As number of electric field lines passing through both the surfaces is equal electric flux associated through both of them is equal.
