Problem
A charged particle, of mass m and charge q , moving horizontally at a speed v , enters a region between two charged parallel plates of length l , between which there is a uniform electric field of strength E in the vertical direction. Which of the following statements is not correct?
(1) It will take a time of vl for the charged particle to pass through the parallel plates.
(2) Whilst between the parallel plates, the charged particle will have an acceleration of mEq .
(3) Whilst between the parallel plates, the charged particle will follow a parabolic path.
(4) Whilst between the parallel plates, the angle between the charged particle's velocity and the electric force acting on it is always 90∘ .
