The mass of a proton is 1847 times that of an electron. A electron and a proton are injected into a uniform electric field at right angle to the direction of the filed with the same initial K.E.

• A. the electron trajectory will be less curved than the proton trajectory.
• B. both the trajectories will be straight.
• C. the proton trajectory will be less curved than the electron trajectory.
• D. both the trajectories will be equally curved.
