Use Gauss’s law to calculate the electric field at a distance r from a point charge +q. Hints: (1) If you use a spherical shell of radius r as your closed surface, then by symmetry the magnitude of the electric field is the same at all points on the sphere, and thus E can be factored out of the integral. (2) Since 4 r^2 is the equation for the area of the surface of a sphere, ´ dA = 4 r^2.

Gauss’s law for electricity gave us a value for the electric field a distance r away (E = (1/4πε0)(qenclosed/r2). You have a conductive solid sphere (radius of a) inside a conductive shell (inner radius of b and outer radius of c). The sphere has a charge of +4Q while the shell has a charge of +10Q. Find the following: a. What is the electric field for r<a? What is the electric field for b>r>a? b. What is the net charge...
#8 Gauss's Law and The Shell Theorem Consider a hollow sphere with charge uni- formly distributed on its surface. Suppose the total charge is Q, where Q may be positive or negative Recall that Gauss's law as we have seen it is: Qenclosed ΣΕ A = EO where A = 47tr2 is the total area of the Gaussian surface Suppose the sphere radius is Ro and r > Ro. In terms of Gauss's Law, the reason why the electric field...
The figure at right shows a 2D cross-section of a charge arrangement containing a point charge +Q surrounded by an uncharged spherical metallic shell with inner radius R and outer radius R2. Your goal is to use Gauss' Law to find out the magnitude of the electric field at the points A and B that are located at distances RA and RB from the center of the sphere as shown in the figure. You will also use Gauss' Law to...

A sphere of radius R has total charge Q. The volume charge density (C/m3) within the sphere is ρ(r)=C/r2, where C is a constant to be determined. The charge within a small volume dV is dq=ρdV. The integral of ρdV over the entire volume of the sphere is the total charge Q. Use this fact to determine the constant C in terms of Q and R. Hint: Let dV be a spherical shell of radius r and thickness dr. What...
