A spherical drop of mercury having a potential of 2.5 v is obtained as a result

A spherical drop of mercury having a potential of 2.5 v is obtained as a result of merging 125 droplets. The potential of the constituent droplets would be

Options

(a) 1.0 V
(b) 0.5 V
(c) 0.2 v
(d) 0.1 V

Correct Answer:

0.1 V

Explanation:

V = n²/³.v = (125)²/³.v = 5².v

2.5 = 2.5 v or v = 0.1 V
