A) \[\frac{V}{n}\]
B) \[nV\]
C) \[n{{V}^{2}}\]
D) \[{{n}^{2/3}}V\]
Correct Answer: D
Solution :
Suppose we have\[n\]identical drops each having radius r, capacitance C, charge q and potential V. If these drops are combined to form a big drop of radius R, capacitance C charge Q and potential V will become: Charge on big drop \[Q=nq\] Capacitance of big drop \[C={{n}^{1/3}}C\] Hence potential of big drop \[V=\frac{Q}{C}=\frac{nq}{{{n}^{1/3}}C}\] \[={{n}^{2/3}}V\]You need to login to perform this action.
