Problem

A particle of mass 1.5×10−6 kg1.5\times10^{-6}\,\text{kg} carrying a charge of 3.0 μC3.0\,\mu\text{C} is traveling at 40 m/s40\,\text{m/s} when it enters a region that is 120 V120\,\text{V} higher in electric potential than the point of entry. Electric forces are the only forces doing work. Calculate the particle’s speed as it leaves the region.
