Eight point charges (can be assumed as uniformly charged small spheres and their centers at the corner of the cube) having value q each are fixed at vertices of a cube. The electric flux through square surface ABCD of the cube is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Each charge has its 1/8 th part of electric field lines inside cube since there are 8 charges.
∴ Net enclosed charge = 
∴ Net flux = 
.
∴ F flux through one surface =
