Consider an infinite long metal table with a surface charge density of 2*10 C/m2. Use Gauss’ law to derive and expression for the electric field at a point P, 3 meters away from the table. You can assume that the table is thick.
a. Find an expression for the net flux through the Gaussian surface.
b. Determine the charge enclosed in your Gaussian surface.
c. Use the answer of b and c to calculate the electric field at point P.
