Two-point charges 
and 
are placed at vertex 
and centre of face 
of the cube as shown in figure. The electric flux passing through the cube is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Using Gauss's law:
Charge 
is at vertex A of the cube. A vertex is shared by 8 cubes, so the flux contribution from 
through this cube is 
.
Charge 
is at the centre of face CDEF. A face center is shared by 2 cubes, so the flux contribution from 
through this cube is 
.
Total flux:
