###### FREE Expert Solution

The electric force that a charge q placed in an electric field E is given by:

$\overline{){\mathbf{F}}{\mathbf{=}}{\mathbf{q}}{\mathbf{E}}}$

From Newton's second law, the acceleration of a charge due to an electrostatic force:

$\overline{){\mathbf{a}}{\mathbf{=}}\frac{\mathbf{F}}{\mathbf{m}}}$

A)

Charge of a proton = 1.6 × 10-19 C

From the electric field equation we're given:

Ex = 500 N/C
