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 field with the same initial K.E.

Options

  1. Athe electron trajectory will be less curved than the proton trajectory.
  2. Bboth the trajectories will be straight.
  3. Cthe proton trajectory will be less curved than the electron trajectory.
  4. Dboth the trajectories will be equally curved.

Correct answer

D. both the trajectories will be equally curved.

Step-by-step solution

K=12mV2K=\frac{1}{2} m V^2. In electric field, Y=qEX22mV2=qEX24KY=\frac{q E X^2}{2 m V^2}=\frac{q E X^2}{4 K} The curvature of the trajectory is proportional to qE/Kq E / K. Since q,Eq, E and KK are same for both particles, hence the trajectories will have the same curvature.
