The ionisation potential of mercury is 10.39 volt. To gain energy sufficient enough to ionise mercury, an electron must travel in an electric field of `1.5xx10^(6)Vm^(-1)` at distance of :

A

`(10.39)/(1.5xx10^(6))m`

B

`10.39xx1.5xxx10^(6)m`

C

`10.39xx1.6xx10^(-19)m`

D

`(10.39xx1.6xx10^(-19))/(1.5xx10^(6))m.`
