A `5C` charge experience a force of `2000 N` when moved between two points separated by a distance of `2 cm` in a uniform electric field. The potential difference between the two points is

Options

A. `8 V`
B. `200 V`
C. `800 V`
D. `20000 V`

Answer

A

Explanation

`E = (2000)/(5)NC^(-1) = 400 NC^(-1)`
Now, `V = Er = 400 xx (2)/(100)V = 8V`
