A metallic sphere of radius R is charged by assembling N electrons (electronic charge e) on it. The total work done is.. A metallic sphere of radius R is charged by assembling N electrons (electronic charge e) on it. The total work done is..
It is only the potential V=(eN)/4RYou can calculate it by integrating -E.dr from infinity to R.E is electric field.E=(eN)/4r2
