Question : 12 of 90

Marks: +1, -0

Within a spherical charge distribution of charge density ρ(r),N equipotential surfaces of potential

V0,V0+∆V,∆V0+2∆V,.....V0+N∆V(∆V>0)

, are drawn and have increasing radii r0,r1,r2....rN, respectively. If the difference in the radii of the surfaces is constant for all values of V0 and ∆V then :
