Question
The mass of a proton is 1847 times that of an electron. An electron and a proton are injected into a uniform electric field at right angle to the direction of the field with the same initial K.E.
The electron trajectory will be less curved than the proton trajectory.
both the trajectories will be straight
the proton trajectory will be less curved than the electron trajectory.
both the trajectories will be equally curved.
Solution
D.
both the trajectories will be equally curved.
The curvature of the trajectory is proportional to qE/K. Since q, E and K are the same for both particles, hence the trajectories will have the same curvature.
