Given below are two statements : Statement I : Rutherfods's gold foil experiment cannot explain the line spectrum of hydrogen atom. Statement II : Bohr's model of hydrogen atom contradicts Heisenberg's uncertainity principle. In the light of the above statements, choose the most appropriate answr from the options given below :

Heisenberg Uncertainity Principle

Assuming Heisenberg Uncertainity Principle to be true what could be the miniumum uncertainity in de–Broglie wavelength of a moving electron accelerated by Potential Difference of 6V whose uncertainity in position is 7/22 n.m.

Bohr's model of atom can explain the spectrum of all except de-Broglie's And Heisenberg Uncertainity Principle
