A disk of radius 
having a uniformly distributed charge 6 C is placed in the 
plane with its centre at 
. A rod of length a carrying a uniformly distributed charge 8 C is placed on the x-axis from 
to 
. Two- point charges -7 C and 3 C are placed at 
and 
, respectively. Consider a cubical surface formed by six surfaces 
. The electric flux through this cubical surface is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
From the figure it is clear that the charge enclosed in the cubical surface is 
. Therefore the electric flux through the cube is
