An electron is projected with uniform velocity along the axis inside a current carrying long solenoid. Then:
A
the electron will continue to move with uniform velocity along the axis of the solenoid.
B
the electron will be accelerated along the axis.
C
the electron path will be circular about the axis.
D
the electron will experience a force at 
to the axis and execute a helical path.
to the axis and execute a helical path.
Text Solution
Verified by ExpertsThe correct answer is:
A
Since 
so force on electron due to magnetic field is zero. So it will move along axis with uniform velocity.
