Hi! I just want to clarify which formula would be best for this problem. Should I go with "V=Ed" or "V=kq/r"
The parallel plates of an air capacitor are separated by 2.25 mm. Each plate carries a charge of 6.50 nC. The magnitude of the electric field of the plates is 4.75x105 V/m. Find the potential difference between the plates.

as you fight your way against the electric field from one plate to the other the force on your charge q is a constant q E so the work done on a unit charge is E * distance = voltage
ohhh!! okay, it makes more sense now :) thank you!!
