Three identical point charges Q are placed at the vertices of an equilateral triangle (length of each side = 2.0 m). If Q = 60 mC, what is the magnitude of the electrostatic force on any one of the charges?
a. 25 N
b. 19 N
c. 14 N
d. 22 N
e. 16 N

Question 2

A point charge Q is placed at the origin. A second charge, 2Q, is placed on the x axis at x = -3.0 m. If Q = 50 mC, what is the magnitude of the electrostatic force on a third point charge, -Q, placed on the y axis at y = +4.0 m?
a. 2.5 N
b. 3.0 N
c. 3.7 N
d. 4.4 N
e. 1.8 N
