1. The problem statement, all variables and given/known data The electric potential of a very large isolated flat metal plate is 2000 V. The plate carries a uniform distribution of charge with surface density σ=1 μC/m2. Determine potential V at a distance x=1 cm from the plate. Assume that point x is far from the edges and that x is much smaller than the size of the plate. 2. Relevant equations To find the magnitude of the electric field I know I have to use: |E|=σ/2ϵ0 3. The attempt at a solution I'll be honest I have no clue how to solve this problem, any pointers in the right direction would greatly help!
