`        If N drops of same size each having the same charge, coalesce to form a bigger drop. How will the following vary with respect to single small drop?              (3)  (i) Total charge on bigger drop (ii) Potential on the bigger drop (iii) Capacitance `

```							Volume would be conserved.Hence,V =nv4/3*pi * R^3 = n*4/3*pi*r^3R^3 = n*r^3...........(1)And as charge is a scalar quantity,Q = nq......(2)From both eqns. we get,Volt = KQ/R => Knq/(rn^(1/3))Capicatance = Q/Volt => nq/[Knq/(rn^(1/3))] => r*n^(1/3)/K Farad.
