Two charges of magnitude -2Q and +Q  are located at points (a,0) & (4a,0) resp. . what is the electric flux due  to  these charges through sphere of radius 3a  with its centre at the origin  ?

Expert Answer:

According to gauss theorem we know that the electric flux through a closed surface enclosing a charge is equal to 1/ε0 times the magnitude of the charge enclosed.
The charge enclosed by the sphere = -2Q
Therefore in this case the electric flux due to these charges through sphere of radius 3a with its centre at the origin,

begin mathsize 14px style straight ϕ equals fraction numerator negative 2 straight Q over denominator straight epsilon subscript 0 end fraction end style
