A) electron will turn to its right
B) electron will turn to its left
C) velocity of the electron will increase
D) velocity of the electron will remain Unchanged
Correct Answer: D
Solution :
In direction of velocity of an electron is in the direction of field, then \[\theta =0{}^\circ \] Force, \[F=qvB\text{ }sin\theta \] \[(\because sin\text{ }0{}^\circ =0)\] \[=0\] Force is zero. So, velocity of an electron will remain same.
