Question

A charged particle (mass $m$ and charge $q$ ) moves along X -axis with velocity V 0 . When it passes through the origin it enters a region having uniform electric field $\vec{E}=-E \hat{j}$ which extends upto $x=d$. Equation of path of electron in the region $x>d$ is

Select the correct option:

A

$y=\frac{q E d}{m V_0^2}(x-d)$

B

$y=\frac{q E d^2}{m V_0^2} x$

C

$\mathrm{y}=\frac{\mathrm{qEd}}{\mathrm{mV}_0^2}\left(\frac{\mathrm{~d}}{2}-\mathrm{x}\right)$

D

$y=\frac{q E d}{m V_0^2} x$

✓ Correct! Well done.
