b. the same everywhere.
c. largest near the negatively charged plate.
d. None of the above.
3.A certain amount of work is required to bring two point charges qnear each other until they are a distance d apart. If the magnitudeof the point charges were doubled to 2q, would the work requiredalso double?
a. yes
b. no
C. It depends on the signs of the charges.
D. None of the above.
