1. Two charges (Q1=-16µC, Q3=- 9µC) are located at fixed positions as indicated in the right figure. (a) Find the electric field produced by the two charges Q1 and Q3 at origin o. (b) Find the magnitude of the electric field in question (a). (c) Find the total electrical force on the charge Q2=-1µC at the point P (3m, 4m).

of 15 > Two charges are placed on the x-axis, +3.00 µC at the origin and -10.0 µC at x = 10.0 cm. Define the positive direction as the +x-direction. #3 Find the electric field E on the x-axis at x = 6.00 cm. At what point(s) xo on the x-axis is the electric field zero?

An electron is placed in a uniform electric field of 32nN/C directed north created by two horizontal parallel plates that are 131fm apart. The electron accelerates from rest, starting at the negative plate. What is the net force and acceleration acting on the electron? How long did it take the electron to get from one side of the plate to the other?
