Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

Three charges are placed on a horizontal line.
Charges q1 = +7 nC and q2 = -3 nC are fixed in
place, with q2 2.0 m to the right of q1. Charge
q3=+5 nC is in equilibrium but free to slide on
the line (but not off of it.)
a. Find the distance between q3 and q1 and
whether q3 is to the right or left of q1.
b. If q3 can move along the line away from its
initial location, is the equilibrium stable or
unstable? How did you decide?
c. If q3 were were on a vertical line instead, so
it could move up and down but not horizontally,
would the equilibrium be stable or unstable for
that motion? How did you decide? m
