[QUOTE="Salah93, post: 4047510, member: 435647"] We have a metal sphere of radius R in the space and resistivity p. At a distance d>R from it we have antoher sphere of metal of radius r<<R and charge q. The 2 spheres intially are at rest. What is the initial potential energy between them? Now the sphere accelerate and collide anelastically. What is the amount of heat Q after this process? P.S This is NOT an homework, but an entrance exame at the university. The question it's very intersting and i solved it. For me is [tex]\frac{1}{4 \pi ε} \frac{q^2}{d}[/tex] and this is for the proprieties of metals. [/QUOTE]
