In This post you will get answer of Q.
An electron travelling with velocity $vec{v}$, enters a region of space in which electric and magnetic fields exist. Then the electron goes uneffected for all values of fields
Solution:
When $ Ene 0 $ and $ Bne 0 $
and E, B and motion of proton (v) are mutually perpendicular, there may be no net force. Force due to E and B cancel each other.
