Question

If an electron and a proton having same momenta enter perpendicularly to a magnetic field, then : (A) curved path of electron and proton will be same (ignoring the sense of revolution) (B) they will move undeflccted (C) curved path of electron is more curved than that of proton (D) path of proton is more curved

Since momenta are same and masses for electron and proton are different, so they will attain different velocities and hence experience different forces. But radius of circular path is depending on momenta so both will be moving on same trajectory (curved path).

Q. If an electron and a proton having same momenta enter perpendicularly to a magnetic field, then :

curved path of electron and proton will be same (ignoring the sense of revolution)

they will move undeflccted

curved path of electron is more curved than that of proton

path of proton is more curved
