A charged particle of specific charge  is released from origin at time t=0 with velocity v = vo(i+j) in uniform magnetic field B=Boi . What are the co-ordinates of the particle at time t= /Bo ?
PLEASE LOOK AT THE POST BELOW IF THE SYMBOLS ARE NOT VISIBLE....

In case the symbols are not visible in above question refer to this modified version:
Q: A charged particle of specific charge "alpha" is released from origin at time t=0 with velocity v = vo(i+j) in uniform magnetic field B=Boi . What are the co-ordinates of the particle at time t=(pi)/Bo(alpha)?

Well I think the value of t at which u r asking...........
should be this........ t = (pi)(alpha) / B0

NO AATISH t = (pi)(alpha) / B DOES NOT SATISFY DIMENTIONAL EQUATION

oh yes!!!!!!!!!!
I m so sorry,,,,,,,,
actually my mistake was that i took m/q as alpha........
:D so silly of me.........
I think i know the answer wait a min.....

hi sniper here u go @=alpha as the particle has velocity in both x and y directions, it will move along a helical path v cross b along negative z so ini. force is along negative z. r=mv/qB T= 2pim/qB at time pi/@ B particle will have completed half a revolution so z coordinate is 2R = -2mv/qB = -2v/@B and after half revol. y coord.=0
