Physics · JEE | Electric Charges and Fields
हिन्दीA point charge \( q \) is placed at a distance \( a/2 \) directly above the center of a square of side \( a \). The total electric flux through the square is:
View Answer & Solution
Correct answer · Option B
\( \frac{q}{6\varepsilon_0} \)
Explanation
Imagine the square as one face of a symmetrical cube of side \( a \) with the charge at its center. Total flux through the cube is \( q/\varepsilon_0 \), so flux through one face (square) is \( \frac{1}{6} (\frac{q}{\varepsilon_0}) \).
