Quizplus · Accepted Answer

The additional charge is placed on the shell which is already carrying a charge Q. As the electric field is a conservative field, the flux through any closed surface is proportional only to the amount of charge within the surface, and not to the distribution of charges. Therefore, the flux through the spherical surface of radius r remains the same, irrespective of the additional charge placed on the shell. Hence, the change in flux is zero, and the correct answer is option D.
