Question

(a) For the charge configuration shown below, draw eight electric field lines. Then

draw a Gaussian surface that encloses both positive charges. What is the net number of

electric field lines exiting the Gaussian surface minus the net number entering the

Gaussian surface? (b) Repeat part (a) except with a Gaussian surface that encloses just

the negative charge. (c) Repeat part (a) except with a Gaussian surface that encloses all

three charges.

(3) For the charge configuration shown below, draw nine electric field lines. Then draw

at least two closed equipotential surfaces

-2q +q +q

which configuration ?
