# Electron deflection

An electron with a speed of $$1.2 \times 10^7 \text{ m/s}$$ moves horizontally into a region where a constant vertical force of $$4.5\times 10^{-16} \text{ N}$$ acts on it. The mass of the electron is $$9.11\times 10^{-31}\text{ kg}$$.

Determine the vertical distance the electron is deflected during the time it has moved $$30\text{ mm}$$ horizontally.
