Problem

An electron (charge −1.60×10−19 C-1.60\times10^{-19}\,\text{C}, mass 9.11×10−31 kg9.11\times10^{-31}\,\text{kg}) is released from rest at a point where the electric potential is 250 V250\,\text{V} higher than at point B. Calculate the speed of the electron when it arrives at point B. Ignore relativistic effects.
