Recap - Stopping a Proton

Part of the Electricity and Magnetism section of Coddy's Physics journey. Lesson 9 of 51.

Challenge

A proton moving to the right at $2\times10^{5}\ \mathrm{m/s}$ enters a uniform field of $500\ \mathrm{N/C}$ that points against its motion. How far $d$ does it travel in the field before it stops?

Try it yourself
