Question

What force will a proton experience in a uniform electric field whose strength is `2.00 * 10^5` newtons per coulomb?

Answer 1

`3.2 xx 10^-14N`

Explanation:

A proton has a charge of `1.6xx10^-19C`.

Therefore, by

`F = QE`

where `F` is force, `Q` is charge and `E` is electric field strength,

`F = 1.6 xx 10^-19 xx 2 xx 10^5 = 3.2 xx 10^-14N`
