1) An electron and a proton having equal momentum, enter a uniform magnetic field at right angle to the field lines. What will be the ratio of their trajectories??

Open in App

Solution

R = mv/qB

For both electron and proton, charge and magnetic field is same. Given, momentum i.e. mv is same.

So, R becomes same.

Ratio of trajectories will be 1:1
