An electrical point charge of 4.50 mC is located on the x-axis at x = 8.00 cm. A second point charge is located on the y-axis at y = 5.70 cm. This second point charge feels of a force of 3.40 x 107 N toward the first charge.
a. Is the second point charge positive or negative?
b. What is the distance between the two charges?
c. What is the value of the second charge?
d. What is the magnitude of the force that acts on the first point charge?
