QUESTION: 1

### The velocity of a charged particle to keep moving in the same direction, in a region where electric and magnetic fields are perpendicular to each other, is _______________

Solution:

As we know, Lorentz force = qE + q (v X B).
Now, as we know, for the particle to move in same direction, the net force on it should be zero.
Therefore, qE + q (v X B) = 0
Solving for v, we get, v = E / B.
