An electron and 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...
 
 
Here, less curved just means that radius is very high. Given that Kinetic energy is same.. => 1/2*mv 2 = K (say) with some rearrangement, v = (2K/m) 1/2 …. => m*v = (2km) ½.… Now, radius r...
