Homework Statement
If E = 6000 V/m, find the potential difference between point X and Y!
a. 2400 V
b. - 2400 V
c. 6000 V
d. - 6000 V
e. 3000 V
Homework Equations
E = V/d
not sure for other equations
The Attempt at a Solution
The electric field of X and Y will be the same. To find the potential difference, we need distance. And by distance, I think the distance should be from the electric charge to the point, but there is none.
So, my desperate move is:
V = E.d = 6000 x 0.5 = 3000 V , where 0.5 is the distance between X and Y?
Am I correct? If yes, why can we use the distance between two points? Also, how to determine whether the potential difference is negative or positive?
Thanks
