A uniform electric field is directed to the left. A particle, initially at rest, having mass 3.2 1021kg and charge +8.10 nC, is released in the region of this electric field. In addition to the electric force, another force acts on the particle making it move 6.00cm to the right. In doing so, the additional force has done 9.4 105 J of work and the particle now has 2.60 105 kinetic energy. Pick the option closest to your answer. (a) What work was done by the electric force? [Select] (b) What is the potential of the starting point with respect to the end point? [ Select] (c) What is the magnitude of the electric field? [ Select]
