An electron and a proton enter a magnetic field perpendicularly. Both have same kinetic energy. Which of the following is true

A

Trajectory of electron is less curved

B

Trajectory of proton is less curved

C

Both trajectories are equally curved

D

Both move on straight line path

Text Solution

Verified by Experts

The correct Answer is:
2
`r=sqrt(2mk)/qB rArr r_(e)/r_(p)=sqrt(m_(e)/m_(p))`
`:’ m_(P)> m_(e)`s0`r_(P)?r_(e)`
Since radius of the path of proton is more, hence it.s trajectory is less curved.
