1.	Two charged particles traverse identical helical paths in a completely opposite sense in a uniform magnetic field B = B0k..(a) They have equal z-components of momenta.(b) They must have equal charges.(c) They necessarily represent a particle-antiparticle pair.(d) The charge to mass ratio satisfy : (e/m)1+(e/m)2=0.
Answer» (d) The charge to mass ratio satisfy : (e/m)₁+(e/m)₂=0.
