Ideally dissipating

Electricity and Magnetism Level 3

A metallic sphere of radius R R is charged to a potential V V . It is now joined to a metallic sphere of radius 2 R 2R by a wire of resistance r Ω r\text{ }\Omega . Half of the value of energy dissipated in the resistance after a long time is:
