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 q1 = +1.92 nC, q2 = +1.07 nC,
and q3 = -2.79 nC.)
A closed spherical surface surrounds two
charges, q2 and q3.
Another charge q1 is to the left of
the sphere.
Charges q1 and q2 are
positive and q3 is negative.
