According to Guass's law the net flux through any closed guassian surface is given by the sum of chages enclosed divided by permeability.
Here q1 and q2 are outside of guassian surface, so they will not have any effect on the flux tgrpugh the surface.
Consider three charges q1 = 7q, q2 = −4q, and q3 = −q (where q = 3.0 µC). (a) What is the total flux through the enclosed surface shown below? ___N · m2/C (b) Now consider a new enclosed surface around the same three charges, shown in the figure below. You wish to add a fourth charge, q4, to the interior of this enclosed surface so that the net flux through the surface is zero. What must be the value...
