Points A and B lie within a region of space where there is a uniform electric field that has no x- or z-component; only the y-component Ey is nonzero. Point A is at y = 8.00 cm and point B is at y = 15.0 cm. The potential difference between B and A is VB - VA = +12.0 V, so point B is at higher potential than point A. (a) Is Ey positive or negative? (b) What is the magnitude of the electric field? (c) Point C has coordinates x = 5.00 cm, y = 5.00 cm. What is the potential difference between points B and C?

Question
Points A and B lie within a region of space where there is a uniform
electric field that has no x- or z-component; only the y-component
Ey is nonzero. Point A is at y = 8.00 cm and point B is at y = 15.0 cm.
The potential difference between B and A is VB - VA = +12.0 V, so
point B is at higher potential than point A. (a) Is Ey positive or negative?
(b) What is the magnitude of the electric field? (c) Point C has
coordinates x = 5.00 cm, y = 5.00 cm. What is the potential difference
between points B and C?
