There are 27 drops of conducting fluid .each drop has radius 'r' and each of them is charged to the same potential V1 . Theyare combined to form a bigger drop the potential of the bigger drop is V2.Find the ratio V2/V1

If q be the charge on each drop

Charge on big drop Q = 27 q

R= radius of bigger drop

4/3 πR^3 = 27 * 4/3 *π * r^3

R=3r

V1 = kq/r

V2 = kQ/R

V2/V1 = 9

V= kq/r

volume will be constant

so 4/3 πR³ = 27 * 4/3 πr³

R=3r

V2/V1 = q2*r/q1*R
