A) \[\frac{-2C}{{{\varepsilon }_{0}}}\]
B) \[\frac{2C}{{{\varepsilon }_{0}}}\]
C) \[\frac{10C}{{{\varepsilon }_{0}}}\]
D) \[\frac{12C}{{{\varepsilon }_{0}}}\]
Correct Answer: A
Solution :
[a] From the figure it is clear that the charge enclosed in the cubical surface is \[3C+2C-7C=-2C.\] Therefore the electric flux through the cube isYou need to login to perform this action.
