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

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
