  • question_answer
    An electron is accelerated through a potential difference of V volt. It has a wavelength associated with them is.            

    A) V volt 

    B) 1837V volt

    C) V/1837volt

    D) \[\sqrt{1837}\]V volt

    Correct Answer: C

    Solution :

    [c]  \[\lambda =\frac{h}{\sqrt{2mqV}}\] and mV = constant \[1837V'=1\times V\text{ or }V'=\frac{V}{1837}volt\]
