Question
In the electric field line diagram for the charge arrangement shown in the figure, 12 field lines emanate from the object of charge +1 C
a) What is the magnitude of the field line flux through closed surface A?
Express your answer as an integer.
b) What is the magnitude of the field line flux through closed surface B?
Express your answer as an integer.
c) What is the magnitude of the field line flux through closed surface C?
Express your answer as an integer.
d) What is the magnitude of the field line flux through closed surface D?
Express your answer as an integer.
e) What is the magnitude of the field line flux through closed surface H?
Express your answer as an integer.
Explanation / Answer
The electric flux is directly proportional to the charge in the closed surface.
Therefore ,
Flux through A = +1-2-4 = -5
Flux through B = +1-2 = -1
Flux through C = +3-2-4 = -3
Flux through D = +3+2-4 = +1
Flux through H = +2-4 = -2
