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.
