Question

QUESTION 4 Find the net electric flux through the spherical closed surface shown in the figure below. The two charges on the right are inside the spherical surface. (Take 91 = +2.02 nc, 92 = +1.10 nc, and q3 = -3.27 nc.) | 0 245 N.mPIC 0-245 N.m31C | 0 - 482 N.m2C 482 N.m2/C

Answer 1

As we know that the net electric flux due to the charge outside the surface is zero.

So now we have to calculate the flux due to the charges inside the surface only.

Flux due to positive charge is positive and due to negative charge it is negative. To net flux is the sum of both the fluxes.

Flux is the dot product of electric field and surface area.

Here area vector and electric field due to charges are in same direction.
