A gaussian surface encloses three point charges \( q_1 = -14 \text{ nC}, q_2 = 78.85 \text{ nC} \) and \( q_3 = -56 \text{ nC} \). The electric flux for the gaussian surface due to these charges is
- A \( 1000 \text{ N m}^2 \text{ C}^{-1} \)
- B \( 7885 \text{ N m}^2 \text{ C}^{-1} \)
- C \(885 \text{ N m}^2 \text{ C}^{-1} \)
- D \(1400 \text{ N m}^2 \text{ C}^{-1} \)
Answer & Solution
Correct Answer
(A) \( 1000 \text{ N m}^2 \text{ C}^{-1} \)
Step-by-step Solution
Detailed explanation
\( Q_{enc} = q_1 + q_2 + q_3 = (-14 + 78.85 - 56) \times 10^{-9} \text{ C} = 8.85 \times 10^{-9} \text{ C} \)…
