1) A charge, q1, of -7 micro-coulombs is located at the origin, a charge, q2, of -9 micro-coulombs is located at x = 0 cm, y = +9.
1) A charge, q1, of -7 micro-coulombs is located at the origin, a charge, q2, of -9 micro-coulombs is located at x = 0 cm, y = +9.2 cm, a charge, q3, of +8 micro-coulombs is located at x = 0 cm, y = -2.5 cm, and a charge, q4, of +3 micro-coulombs is located at x = 5.1 cm, y = 0 cm. What is the magnitude of the total electric force on q2 (charge on the +y axis) in Newtons?
