Correct answer: B. 5Q ε _ 0

Two charges of 5Q and - 2Q are situated at the points ( 3a, 0 ) and ( - 5a, 0 ) respectively. The electric flux through

As can be seen from the figure above, only the $5Q$ charge is inside the spherical region.

The formula to calculate the flux through the surface is given by

$ϕ = \dfrac{{q}_{enc}}{{ε}_{0}} . . . \left(1\right)$

From equation $( 1 )$ , the flux through the given surface can be calculated as follows:

$ϕ = \dfrac{5Q}{{ε}_{0}}$
