The electric field ( \(\overrightarrow{\mathrm{E}}\) in \(\mathrm{NC}^{-1}\) ) in a region is given by \(\overrightarrow{\mathrm{E}}=3 \hat{\mathrm{i}}+5 \tilde{\mathrm{i}}\). The net electric flux through a square area of side \(2 \mathrm{~m}\) parallel to \(\mathrm{y}-\mathrm{z}\) plane is
- A \(3 \mathrm{NC}^{-1} \mathrm{~m}^2\)
- B \(6 \mathrm{NC}^{-1} \mathrm{~m}^2\)
- C \(12 \mathrm{NC}^{-1} \mathrm{~m}^2\)
- D \(24 \mathrm{NC}^{-1} \mathrm{~m}^2\)
Answer & Solution
Correct Answer
(B) \(6 \mathrm{NC}^{-1} \mathrm{~m}^2\)
Step-by-step Solution
Detailed explanation
The net electric flux through a square area \(A=2 \times 2=4 \mathrm{~m}^2\) parallel to \(y-z\) plane only, as or.ly \(\mathrm{i}\) component will cause any flux \(\therefore\) Flux…
