The electric field at the surface of a black box indicates that the outward flux through the surface of the box is 8.0x10 to the power of 3 NM2/C. (a) What is the charge inside the box. (b) If the net outward flux through the surface of the box were zero, could you conclude that there were no charges inside the box? Why of why not?

Expert Answer:

(b)The amount of net flux through a body depends on the net charge contained in a body. If net flux outwards flux the surface of the box is zero, then it can be inferred that there is no net charge inside the body. The body may have equal amount of positive and negative charges. Hence, net outward flux is zero.
