Explanation:Problem 2:

Two point particles have charges q1 and q2 and are separated by a distance

d. Particle q2 experiences an electrostatic force of 12 milliN due to particle

q1. If the charges of both particles are doubled and if the distance between

them is doubled, what is the magnitude of the electrostatic force between

them (in milliN)?

Answer: 12

Solution: The magnitude of the initial electristatic force is

mN

Problem 3:

Two identical point charges +Q are

located on the y-axis at y=+d/2 and

y=-d/2, as shown in the Figure. A third

charge q is placed on the x-axis. At

what distance from the origin is the net
