Work function of Zn is 3.74 eV.If the sphere of Zn is illuminated by the X-rays of wavelength 12Å,the maximum potential produced on the sphere is ………..(`h=6.625xx10^(-34)Js)`

Text Solution

Verified by Experts

`eV_(0)=(hc)/(lambda)-phi`
`therefore V_(0)=(hc)/(lambdae)-(phi)/(e )`
`=(6.625xx10^(-34)xx3xx10^(8))/(12xx10^(-10)xx1.6xx10^(-19))`
`-(3.74xx1.6xx10^(-19))/(1.6xx10^(-19))` `thereforeV_(0)=1031.4V`
