What possibly can be the ratio of the de Broglie wavelengths for two electrons each having zero initial energy and accelerated through 50 volts and 200 volts?
Text Solution
Verified by ExpertsThe correct answer is:
D
We know that, de broglie wavelength,
Where, 
potential
mass of electron
So, 
Given that electrons are accelerated through 50 V and 200 V respectively, therefore,
