An electron beam is moving between two parallel plates having electric field \[1.125\times {{10}^{-6}}N/m\]. A magnetic field \[3\times {{10}^{-10}}T\] is also applied so that beam of electrons do not deflect. The velocity of the electron is [MH CHT 2004]

• A.   \[4225\ m/s\]    
• B.   \[3750\ m/s\]
• C.   \[2750\ m/s\]    
• D.   \[3200\ m/s\]
