A charge +3 MC moves from point 1 (at rest) to point 2, where 1 is at a potential of +1000 V and 2 is at a potential of -1000 V. a) How much work in Joule, is done by the electric force on the charge? [Enter only the number (without the unit) up to three decimal places] b) If the charge has 2 g mass, what is the speed in m/s, of the charge when it reaches point 2? [Use work-kinetic energy theorem or conservation of energy] Enter only the number (without the unit) up to 2 decimal places
