Two electrons are moving with same speed v. One electron enters a region of uniform electric field while the other enters a region of uniform magnetic field, then after
some time de Broglie wavelengths of two are ${\lambda }_1$ and ${\lambda }_2$ respectively. Now,

• A

  ${\lambda }_1={\lambda }_2$

• B

  ${\lambda }_1>{\lambda }_2$

• C

  ${\lambda }_1<{\lambda }_2$

• D

  ${\lambda }_1\text{ can be greater than or less than }{\lambda }_2$
