1. The problem statement, all variables and given/known data

Determine the potential 1.0 mm from the negative plate of a pair of parallel plates separated by 4.0 mm and connected to a 24 V battery.

2. Relevant equations
w = EPEa - EPEb
v = kq^2/r^2

3. The attempt at a solution
I'm not exactly sure how to start. Can someone tell me if I even have the right equations? Thanks!

Potential between plates

1. The problem statement, all variables and given/known data
Determine the potential 1.0 mm from the negative plate of a pair of parallel plates separated by 4.0 mm and connected to a 24-V battery.

2. Relevant equations
w = EPEa-EPEb
V= kQ^2/r^2

3. The attempt at a solution
I'm not exactly sure what is being asked and not sure if I even have the correct equations? Could someone point me in the right direction? Thanks

Hi matt72lsu!

Voltage is electric potential difference.

Two threads merged. Matt, do not multiple post. The Intro Physics forum here is the correct place for your questions.
