The surface charge density of an infinite sheet of charge is 9.00 X 10^-6 C/M^2. What is the magnitude of electric field near the center of the sheet?
Consider two concentric spherical shells, one with radius R, and with the radius 2R. Both have the same charge Q. At a point just inside the outershell, the magnitude of the electric field is A. 2kQ/R B. KQ/R C. KQ/2R D. 2kQ/R^2
The probelem belongs to electrostatics chapter and calculation is related to electric field and potential.
A static electric charge is distributed in a spherical shell of inner radius R_1 and outer radius R_2. The electric charge density is given by Rho=a+br, where, r is the distance from the center, and zero everywhere else. (a) Find an expression for the electric field everywhere in terms of r. b) Find expressions for the ele
A (infinitley long) cylindrical non-conducting tube, inner radius a and outer radius b, with charge density p0 sits in a vacuum.
