Question
Two electrons are moving with the same speed v. One electron enters a region of uniform electric field while the other enters a region of uniform magnetic field, than after sometime if the de -Broglie wavelengths
Options
A.λ1 = λ2
B.λ1 > λ2
C.λ2 > λ1
D.None of these
Solution
We have work is done by only electric field. Thus if 
decreases, & thus momentum of electron decreases & vice - avers, while in magnetic field 
remains constant
