Ok so charges aren't involved. And if the field is uniform I would use: (Delta)V=-E*(delta)r But how do i get the field E with all these unit vectors? Would I just plug in the differences of x and y coordinates of point a and b into (3 i - 1 j) x 10^5 N/C to find the field?

Hey guys, I have a problem that I really have no idea what to do. It was discussed in class that we do not need to know how to integrate or use the dot product-- any of the complex stuff. 1. Homework Statement The electric field in a given region in space is given by (3 i - 1 j) x 10^5 N/C...

Hey guys, I have a question regarding fields. I hope you guys can guide me to the right answer! :biggrin: The question states: A charge Q = 42 nC is uniformly distributed over a half spherical shell of radius R = 48 cm. What is the potential at the center? I didn't learn Gauss's Law in class...

Hello, so this was a past assignment question that I attempted. I got the right answer but in an incorrect way (I guess my thinking was not based on the concept?) 1. Homework Statement Three point charges of charge Q = 10...
