Question 3. [10]
Part 1:
Suppose a region of space has a uniform electric field, directed towards the right, as shown in the figure.
Which statement about the electric potential is true?
E
A
C
В
(1) The potential at points A and B are equal, and the potential at point C is lower than the potential at
point A.
(2) The potential at all three locations (A, B, C) is the same because the field is uniform.
(3) The potential at point A is the highest, the potential at point B is the second highest, and the potential
at point C is the lowest.
(4) The potential at points A and B are equal, and the potential at point C is higher than the potential at
point A.
Part 2:
Two point charges of +1.0 µC and -2.0 µC are located 0.50 m apart. What is the minimum amount of
work needed to move the charges apart to double the distance between them? (k = 8.99 x 109 N · m²/C?)
