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 `vecE=-E hatj` which extends upto x=d . Equation of path of electron in the region . `x gt d` is :

A

`y=(qEd)/(mV_0^(2))((d)/(2)-x)`

B

`y=(qEd)/(mV_0^(2))(x-d)`

C

`y=(qEd^(2))/(mV_0^(2))x`

D

`y=(qEd)/(mV_0^(2))x`
