5. In the diagram below three small plastic spheres are at two corners of an equilateral triangle with sides 1.0 cm. The charges are q1 = +40.0 nC, q2 = - 40nC, and q3 = - 30nC, as shown. What is the net electric force on q3, the charge at the lower-left corner of the equilateral triangle? 9, to 23 So!
