Halliday, Resnick & Walker — Force and Motion-I: Problem 27

27 A subatomic particle moves horizontally, with a speed of \(1.5 \times 10^7 \text{ m/s}\), into a region where a uniform vertical electric force of \(5.5 \times 10^{-16} \text{ N}\) acts on it. Assuming the subatomic particle is an electron (the mass of the electron is \(9.11 \times 10^{-31} \text{ kg}\)), find the vertical distance the particle is deflected during the time it has moved \(35 \text{ mm}\) horizontally.
