Three charged particles are placed at locations on a straight line.
The charge A is −5.00 μC and is located at x = 0.20 m.
Charge B is −3.50 μC and is located at x = 0.35 m.
The third charge has an unknown amount of charge, but is placed at x = 0.60 m.
The total force on charge A turns out to be zero.
Ignore gravitational effects in this problem.
Call "to the right" positive.
(A) How many excess electrons make up the charge A?
(B) Draw the free body diagram of charge A.
(C) What is the charge located at C?
