Two electron are moving with same speed. One enter a region of uniform electric field along the direction of electric field while other enter a region of uniform magnetic field. After some time if the de-Broglie wavelength of the two electrons are respectively l1&l2 then –
A
l1 = l2
B
l1>l2
C
l1<l2
D
None
Answer
l1>l2
Explanation
Solution
In magnetic field l remain constant.
In electric field l will increases.
