Part 2) A charged particle q1 = 181 X 1019 C is generating a radial electric field outwards. Another positive charge with (12 = 2.44 X 1019 C and m; = 7.00 x 1031 kg is brought into this electric field. Calculate the electrical potential at distance r = 283 pm from the charge q]. V1 = l:l V Part 3) The charge an moves from the point with the potential calculated in Part 2 to a position with a lower potential, V2 = 183 V. If its initial velocity is v,- = 3.18 m/s, calculate its final kinetic energy. Part 1) Consider a positively charged particle creating an electric field. Which of the above shows an equipotential surface? [:1 A: parallelogram centred on the point charge. [:1 B: a circle passing through the point charge. C: a circle with the point charge at its centre. [:1 D: a circle at a distance from the point charge. When moved between any two points of the equipotential surface, on which surfaces will the potential energy of a charged particle remain the same? DA [:13 lo i'ln
