Question: Imagine that some protons are moving to the left at the same time that some electrons are moving to the right past the same location.

Imagine that some protons are moving to the left at the same time that some electrons are moving to the right past the same location.
(a) Will the net current be (1) to the right, (2) to the left, (3) zero, or (4) none of the preceding?
(b) In 4.5 s, 6.7 C of electrons flow to the right at the same time that 8.3 C of protons flow to the left. What are the direction and magnitude of the current due to the protons?
(c) What are the direction and magnitude of the current due to the electrons?
(d) What are the direction and magnitude of the total current?
