Two metallic spheres of radii R and 2R charged so that both of these have same surface charge density sigma - Physics - Electric Charges and Fields

Question

Two metallic spheres of radii R and 2R charged so that both of
these have same surface charge density sigma If they are connected
to each other with a conducting wire, in which direction will the
charge flow and why?

Dear Student,

potential at radius of sphere R  V=k4πR2σR=k4πRσpotential at radius of sphere 2R   V'=k16πR2σ2R=k8πRσV'=2Vhence the charg flow from the higher potential to lower potential from the radius of 2R to radius R
Regards
