A) curved path of electron and proton will be same (ignoring the sense of revolution)
B) they will move undeflected
C) curved path of electron is more curved than that of proton
D) path of proton is more curved
Correct Answer: A
Solution :
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). \[\because \] \[r=\frac{mv}{qB}=\frac{p}{qB}\]
