Equipotential surface A has a potential of 8350 V,while equipotential surface B has a potential of 16100 V. Aparticle has a mass of 5.42 x 10-2kg and a charge of +4.6 x 10-5C. The particle has a speed of 8.95 m/s on surfaceA. An outside forceis applied to the particle, and it moves to surfaceB, arriving therewith a speed of 21.9 m/s. How much work is done by the outside force in moving the particle from A to B?
