Question

explain

A thin, square, conducting plate 43.0 am on a side lies in the xy plane. A total charge of 4.10 x 10 c is placed on the plate. You may assume the charge density is uniform. (a) Find the charge density on each face of the plate. 217 e-7 x what is the definition of surface charge density? C/m2 (b) Find the electric field just above the plate. 25044.21 What the equation for the electric field due to a uniform surface charge? N/c direction (c) Find the electric field just below the plate. NIC magnitude direction downward Need Help?

Explanation / Answer

a) charge density on the each surface of the plate is = 1/2(q/A) = 1/2*4.1*10^-8/0.43^2 = 1.109*10^-7 C/m^2

b) eelctric field just above the plate = sigma/e0 = 1.109*10^-7/8.85*10^-12 = 12.53 kN/C upward

c) just below tha plate electric field is acting -12.53 kN/C downward
