I was reading a chapter on Capacitors in whichcapacitors where it was asked that if there are 2whether given two spheres, each carrying a charge q$q$ and of radius r$r$ and 2r$2r$, then will charge flow. between them?
I assume the answer should be no as both are having the same charge (that is what I learned in electrostatics that charge redistributes in such a way that charges become equal).But But the book says that charge will flow. My friend told me that their potential will become equal.But But why will their potential become equal (if it does)?
