A chаrged pаrticle оf mаss 5 × 10-6 kg and charge +[q] × 10-3 C mоves frоm position a to position b under the influence of an electric field. A velocity-versus-position graph is shown. Given that v = 50 m/s, determine the electric potential difference between positions a and b, Vb − Va (in volts). Note: The potential difference may be positive or negative. [Hint: use total energy conservation.]
