A closed surface encloses a net charge of `-3.60 muC`. What is the net electric flux through the surface?
(b) The electric flux through a closed surface is found to be `780 N-m^2//C`. What quantity of charge is enclosed by the surface?
(c) The closed surface in part (b) is a cube with sides of length 2.50 cm. From the information given in part (b), is it possible to tell where within the cube the charge is located? Explain.

Answer

C

Explanation

a. `phi_("total")=q_("in")/epsilon_0`
b. `q_("in")=(phi_"total")(epsilon_0)`
