The charged particle enter at an angle of 45degree with the magnetic field then, what will be the path of particle?

Question

anonymous · Answer

do you know how to find the direction of the force on a moving charged particle?!

anonymous · Answer

yep...i just want the anwer of above Q.....options are a)straight line   b)circular    c)ellipse     d)spiral

anonymous · Answer

what do you think would happen??

when charged particle enters perpendicular what is the path of the particle?

anonymous · Answer

yes its circular path...but while complition of circle if the particle goes outside the field then it moves in a straight line...

anonymous · Answer

yes we are not worried about that.. now think of it this way.. the velocity is 45 degrees.. so.. a component of it is perpendicular that gives it a circular motion
another component is parallel to the field which has no effect.. 

so what do you think happens when you a particle which is describing both a circle and moving ahead?

got it...its spiral... thanx
