An electron beam moves undeflected in a Lorentz Field given by .Then the velocity of electron beam is
detailed solution
Correct option is B
Lorentz force F→ = −eV→ ×B→ +−eE→ = 0(−e)V →× B →+(−e)E→=0⇒(vxi^+vyj^+vzk^)×(0.5k^)=(3×104)i^⇒0.5×vy×(i^)=(3×104)i^⇒vy=6×104m/s∴V→=6×104j^m/sTalk to our academic expert!
