Question 10 2 out of 2 points In the drawing below, E-4.0N/C and d = 1.5m. Calculate the work done by the electric field in moving a +5.0x10-9C charge from A to B. Be sure to include-sign if your answer is negative. Your answer needs to be in J but you don't need to enter the unit in your answer for this question.Note: the answer for this question is very small and using scientific notation will help. This system uses E in place of x10 so for example to enter 3x10-24 type 3E-24 in the answer box. Selected Answer: 2.6E-8 Question 11 2 out of 2 points n the situation in diagram c above, calculate the potential energy difference between the+5.0x10 C charge at B and at A.

Selected Answer: -2.6E-8 Question 12 0 out of 2 points For the situation in diagram c above, calculate the potential difference between A and B. Be sure to include sign if your answer is negative. Your answer needs to be in V but you don't need to enter the unit in your answer for this question. Selected Answer-6

Explanation / Answer

1. The work done is = V.dl

-qE.dl = q x E x L cos(30) = - 2.589e-8 J

2. The potential difference = work done = -2.589e-8 J

3. Potential diffence = V= - int(E.dl) = - 5.196
