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. \[{{\lambda }_{1}}\]can be greater than or less than \[{{\lambda }_{2}}\]
