1. Two small metal spheres with masses 2.0g and 4.0g are tied together by a 5cm long massless string and are at rest on a frictionless table. Each sphere has a (mue)c charge.
The string is cut, what are the velocities of the sphere when they are far apart
I know two conservative qualities are at play, electric energy, and I'm not sure of the other
I tried using change under the curve with r being the variable (kQq/r) being equal to work and then said mv^2/2. However I can't articulate how I am sure this is the wrong approach.
What is the right way/approach?
