Expert Answer
Volume of bigger drop fromed from n drops of same size = n×(4/3)πr3 = (4/3)πR3
wher r and R are radius of small drop and bigger drop respectively. hence R = n1/3×r
if each small drop had the charge q coulomb, then charge on boigger drop will be (nq) Coloumb
potential Vb of bigger drop is given by
