Problem

In a certain region of space, the electric field is along

+y

-direction and has a magnitude of

400 \text{ V/m}

. What is the potential difference from the coordinate origin to the following points? a.

x = 0, y = 20 \text{ cm}, z = 0

x = 0, y = -30 \text{ cm}, z = 0

x = 0, y = 0, z = 15 \text{ cm}
