Question

The potential difference between a pair of charged parallel plates 0.05 m apart is 50 volts. What is the electric field intensity between the plates?

Answer 1

I know \[E=kQ/r^2\] and \[Q=W/V\] but I'm not sure how to find W, or if I can do the problem without finding W

Answer 2

what do you know about the field between parallel plates?

that is the key here.

Answer 3

it's constant, the same wherever you are in the space between the plates...
