Electric Field mcq question image

A. due to $${q_1}$$ and $${q_2}$$ only

B. due to $${q_2}$$ only

C. zero

D. due to all

Answer : due to all

Solution :
The flux through the Gaussian surface is due to the charges inside the Gaussian surface. But the electric field on the Gaussian surface will be due to the charges present in side the Gaussian surface and outside it. It will be due to all the charges.
