Question

Consider the charge configuration and a spherical Gaussian surface as shown in the figure. When calculating the flux of the electric field over the spherical surface, the electric field will be due to. (A) q2 (B) only the positive charges (C) all the charges (D) +q1 and -q1

At any point over the spherical Gaussian surface, net electric field is the vector sum of electric fields due to

+ q_{1}, - q_{1}

and

q_{2} .

Don't confuse with the electric flux which is zero (net) passing over the Gaussian surface as the net charge enclosing the surface is zero.
Hence, the correct option is (c).
