Answer #1

Part A) Two particles with positive charges q1 and
q2 are separated by a distance s.
Along the line connecting the two charges, at what distance from
the charge q1 is the total electric field from the two charges
zero?
Express your answer in terms of some or all of the
variables s,
q1,
q2 and
k =14πϵ0. If
your answer is difficult to enter, consider simplifying it, as it
can be made relatively simple with some work.

q3 = 6.40 * 10^-19 C is moved gradually along the x axis from x = 0
to x = 5.0 m. At what values of x will the magnitude of the
