If an electron and a proton are projected at right angles to a uniform magnetic field with the same kinetic energy

Options

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

Answer

2

Explanation

`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.
