Coulomb's Law
Three point charges are positioned as shown in figure 2 with a 2x10-4 C charge .5 m north
of the origin, a -6x10-4 C charge 1 m east of the origin and a 3x10-4 C charge at the origin.
1. What is the magnitude and direction of the force that the 2x10-4 C charge exerts on the
3x10-4 C charge at the origin?
2. What is the magnitude and direction of the force that the -6x10-4 C charge exerts on the
3x10-4 C charge at the origin?
3. What is the magnitude and direction of the total force on the 3x10-4 C charge exerted
by the other two charges? Answer this question with an analytical solution and a rough
graphical solution.
