A charged particle passes through a unif...

A charged particle passes through a uniform electric field existing between the parallel plates of a capacitor. The length of each plate is `l`. Its initial velocity is parallel to the plates. When it emerges from the field, its deflection from its initial path is `delta`, and its angular deflection from its initial directioin `theta`. Then,` theta` is equal to

A

`delta//l`

B

`2delta//l`

C

`delta//2l`

D

none of these
