Questions
A beam of electrons is moving with constant velocity in a region having electric and magnetic fields of strength 20 Vm-1 and 0.5 T at right angles to the direction of motion of the electrons. What is the velocity of the electrons ?
detailed solution
Correct option is B
Bev=eE or v=E/B∴ V=200⋅5=40m/sTalk to our academic expert!
