Particles qn, q2, and q3 are in a straight line. Particles q1 = -5.00 x 10-6 C,92 = +2.50 x 10-6 C,
and q3 = -2.50 x 10-6 C. Particles q1 and q2 are
separated by 0.500 m. Particles q2 and q3 are
separated by 0.250 m. What is the net force on q2?
Remember: Negative forces (-F) will point Left
Positive forces (+F) will point Right
