Machine generated alternative text: a c b Figure 1 _ There is a uniform electric field in the negative y direction The three points ot interest a, b and c exist where points a and b are displaced horizontally and point c lies vertically above point A region of space contains an electric field described by E = -8.535 N/C Consider three points in space a = (1.57, 1.25) m, b = (2.86, 1.25) m, and c = (2.86, 2.65) m. How much work does an external force need to do on a particle witn a charge ot +4.17 x 10-18 C to move it: part 1) From a to b? Wu•b part 2) From b to c? part 3) From c to a?

 

Machine generated alternative text: Your answer is partially correct Note: Your answers should be correct to 3 significant figures. Feedback tor Part 1) You have correctly answered this part Marks for this submissiom 0.33/0.33. Feedback tor Part 2) In this case the particle is moving in the -Fj directiom You will need to do positive work to move a positive panicle against the field. - 8.53 dy q x 8.53 x (Y2 — Yl)• Marks for this submissiom 0.00/0.33. This submission attracted a penalty of 0.11 Feedback tor Part 3) You have correctly answered this part Marks for this submissiom 0.33/0.33. A correct answer is 0, which can be typed in as follows: A correct answer is 4.97e — 17, which can be typed in as follows: 4.972-17 A correct answer —4.97e — 17, which can be typed in as follows: -4.972-17
