Homework Statement


Two small objects, A and B, are fixed in place and separated by 2.46 cm in a vacuum. Object A has a charge of +1.18C, and object B has a charge of -0.937C. How many electrons must be removed from A and put onto B to make the electrostatic force that acts on each object an attractive force whose magnitude is 32.3 N?



Homework Equations


I using Coulombs law and im plugging Qa+Q for Qa and Qb-Q for Qb. I end up getting a quadratic but only getting imaginary results
