Question

For this problem, let Q1 > 0 and Q2 = - Q1.

(Warning! This may change if you do this question twice!)

Consider moving a negatively charge object, at a constant speed, along each of the four paths shown and labeled A, B, C, and D. The paths start at one of the two black dots and end at the arrow heads on the path. (So, for example, moving the negative charge along the path A means the charge starts at the dot on the right circle and ends up at the bottom of the left circle.)

Below are rankings of these paths. Which one of thes rankings correctly lists these paths in order of the change in potential energy of the negative charge as it is moved along the path? In other words, the "highest" for "first" path should have the largest change in potential energy.

As always, the change is final (arrow head) minus initial (dot), negative numbers are less than positive numbers, and morenegative numbers are less than less negative numbers.

A = B = C = D

C = D > A = B

A > B > C > D

C > B > D > A

A = B > C = D

D > A > C > B

A > D > B > C

D > C > B > A

B = C > A = D

C > D > A > B

A = D > B = C

B > A > D > C

B > C > A > D

Please help in explaining this

1)

A = B = C = D

2)

C = D > A = B

3)

A > B > C > D

4)

C > B > D > A

5)

A = B > C = D

6)

D > A > C > B

7)

A > D > B > C

8)

D > C > B > A

9)

B = C > A = D

10)

C > D > A > B

11)

A = D > B = C

12)

B > A > D > C

13)

B > C > A > D

Explanation / Answer

option 6 is suitable here D > A > C > B

because here negative charge is moving from D to a negative charge circle of charge -Q1 so repulsive force against the repulsive force we should do more work when compared wit in the path A and same for the C,B
