Electron enters into a magnetic field at an angle of 60°, its path will be?
A. straight line B. circle C. parabola D. helix

Best Answer
option d is correct
it would definitely go in helical path as F=evBsin(60)
e= charge on electron
v = velocity
B = magnetic field
Force is perpendicular to velocity in magnetic field (as per left hand rule)
as the particle has a initial velocity it would not let it go round a circle( so option 'b' is wrong )
as there is no electric field to cancel out magnetic field (so option a is also wrong )
it is not a parabolic path as it does not come out of magnetic field (so option c is wrong)
and last but not the least as stated above option "d" is correct.........................
no need to say thanx
