1. The problem statement, all variables and given/known data Two Charged spheres are positioned on a horizontal, frictionless insulating surface, as shown below. I attached the image at the bottom of the post. 2. Relevant equations Coulombs Law and F=ma 3. The attempt at a solution I plugged in ((8.99 x 10^9)(5.0 x 10^-7)(5.0 x 10^-7))/(1.25)^2 Once I got the answer I used F=ma to find the acceleration which is 9.59 x 10^-2 m/s I believe this is the correct answer. I was wondering if one of the spheres is negative would I go about answering the question in the same way. Or would I have to factor in other things.
