Question

Consider the spherical Gaussian surface shown in the figure below. It is situated near a point charge Q which is located a distance 7r from the center of the sphere and outside the Gaussian surface. Compute the net electric flux through this surface. (Use any variable or symbol stated above along with the following as necessary: ?0.)

The answer needs to be in equation form.

Explanation / Answer

solid angle subtended by any closed curve at any external points is zero;

hence from gaus law;

E.ds=Qin/epsilon

E*solid angle*r^2=Qin/epsilon

hence,

E=0
