$3.2 xx 10^-14N$

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,

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

What force will a proton experience in a uniform electric field whose strength is 2.00 * 10^52.00 * 10^5 newtons per coulomb?
