Question
A charge q is placed at the centre of the cubical vessel (with one face open) as shown in figure. The flux of the electric field through the surface of the vessel is
Options
A.zero
B.q/ε0
C.q/4ε0
D.5q/6ε0
Solution
(C) Total flux through closed cubical vessel = q/ε0.
& Flux through one face =
So, total flux passing through given cubical vessel is =
; (as vessel has 5 faces)
& Flux through one face =
So, total flux passing through given cubical vessel is =
; (as vessel has 5 faces)Create a free account to view solution
