A point charge – 5 µC is at a distance 5 cm directly above the centre of a square of side 10 cm.
The magnitude of electric flux through this square is:
- A \(\frac{5 \times 10^{-6}}{3 \varepsilon_0} N C ^{-1} m^2\)
- B \(\frac{5 \times 10^{-5}}{6 \varepsilon_0} N C ^{-1} m^2\)
- C \(\frac{6 \times 10^{-6}}{5 \varepsilon_0} N C ^{-1} m^2\)
- D \(\frac{5 \times 10^{-6}}{6 \varepsilon_0} N C ^{-1} m^2\)
Answer & Solution
Correct Answer
(D) \(\frac{5 \times 10^{-6}}{6 \varepsilon_0} N C ^{-1} m^2\)
Step-by-step Solution
Detailed explanation
\( q = -5 \times 10^{-6} C \) \( \Phi = \frac{q}{6 \varepsilon_0} \) \( |\Phi| = \frac{|-5 \times 10^{-6}|}{6 \varepsilon_0} \) \( |\Phi| = \frac{5 \times 10^{-6}}{6 \varepsilon_0} N C^{-1} m^2 \)
