Find the flux of the electric field through a spherical surface of radius R due to a charge of 10
−7
C at the centre and another equal charge at a point 2R away from the centre.Given: Magnitude of the two charges placed =10
−7
C.
We know: from Gauss's law that the flux experienced by the sphere is only due to the internal charge and not by the external one.
Now ϕ=∮Eds=
ε

Q
So, the flux will be
ϕ=
8.85×10
−12
10
−7
ϕ=1.1×10
4
N−m
2
/C.
