The trajectory of an electron, initially moving at speed $v$, in the uniform electric field between two parallel plates is illustrated. The vertical deflection $x$ is recorded at the right-hand edge of the plates. The separation between the plates is reduced to half its original value. The potential difference across the plates stays unchanged. What will the electron’s new deflection be if it starts with the same initial speed $v$?
- A$x$
- B$\sqrt{2}x$
- C$2x$
- D$4x$
