careful measurement of the electric bell at the surface of a black box indicate that the net outward flux through the surface of the box is 8 ×10 ^3 Nm2/ C a) what is the net charge inside the box?
b) if the net output plugs through the surface of the box were zero could you conclude that there where no charge inside the box question mark by or why not?
