A point charge Q is placed on the x axis at the origin. An identical point charge is placed on the x axis at x = -1.0 m and another at x = +1.0 m. If Q = 40 mC, what is the magnitude of the electrostatic force on the charge at x = +1.0 m?
a. 29 N
b. 14 N
c. 11 N
d. 18 N
e. 7.0 N
Question 2
A point charge Q is placed on the x axis at x = -2.0 m. A second point charge, -Q, is placed at x = 1.0 m. If Q = 60 mC, what is the magnitude of the electrostatic force on a 40-mC charge placed at the origin?
a. 16 N
b. 27 N
c. 32 N
d. 11 N
e. 3.0 N
