Electric potential of charged particles
The two red points in the above diagram are charged particles
A
and
B
fixed on the
-axis. The blue curves represent the electric potentials generated by
A
and
B
as a function of the position on the
-axis. Which of the following statements is correct?
a) Particles
A
and
B
have the same sort of charges.
b) The direction of the electric field at point
O
is
direction.
c) The quantity of the electric charge of particle
A
is greater than that of particle
B
.
