A square metal plate carries a uniform charge of 12.0 nC.The electric field directly above the surface is 33 kV/m. What is the length of the plate?
Homework Answers
As charge is distributed on both sides of plate, therefore
Where A is area.
Electric field is given by
q = 12×10-9 C
E = 33000 V/m
8.85×10-12
Putting values
L2 = 0.02054
L = 0.143 m= 14.3 cm

Please answer the question below:
The electric potential of a very large isolated fat metal plate is V_0. It carries a uniform distribution of charge of surface density sigma (C/m^2), or sigma/2 for each surface. Determine V at a distance x from the plate. Consider the point x to be far from the edges and assume x is much smaller than the plate dimensions.

Two square metal plates are placed parallel to each other, separated by a distance d= 2.28 cm. The plates have sides of length L = 0.690 m. One of the plates has charge Q= + 2.34×10-6 C, while the other plate has charge -Q. Calculate the magnitude of the electric field between the plates, not close to the edge, i.e., assume a uniform surface charge distribution.
