Two insulating spheres have radii 0.3cm and 0.5cm, masses 0.1kg and 0.7kg and uniformly distributed charges of -2 [tex]\mu[/tex]C and 3 [tex]\mu[/tex]C. they are released when the distance from their center are 1m apart. How fast will each be moving when they collide.(adsbygoogle = window.adsbygoogle || []).push({});

Firstly, what is the radius of the sphere use for? Secondly, I calculated the electric potential energy of the system but what is this energy equivalent to? Lastly, how can we solve this question if the spheres were conducting spheres?
