Homework Statement
A total charge of 21 μC is applied to a thin, 1μm square metal plate 72 cm on a side.
Find the electric field strength near the plate's surface, far from the edges.
Homework Equations
I think E = kq/r^2, but I really don't know.
The Attempt at a Solution
I am having a hard time figuring out where to start. I know I must find the electric field strength (i.e magnitude), but where do I begin and what do I do to find it. I just know that E = kq1q1/r^2, but there is no second charge so it must be kq1/r^2 correct? Do I use that or something else?
