–Coulomb Law Illustrated
If charges are of same magnitude (and same separation),
all the forces will be the same magnitude, with different
Electric “field lines” tell a positive
charge which way to move.
For example, a positive charge itself
has field lines pointing away from it,
because this is how a positively-charged
“test-particle” would respond if placed
in the vicinity (repulsive force).
electric potential = electric potential energy/charge
