What is the moment of inertia of the aluminum ring, Iring, shown in the figure where mass M = 61 grams; and inner and outer radii, a = 6.35 cm and b = 7.6 cm, respectively.
You have a solid, nonconducting sphere inside and concentric with ahollow conducting sphere.The inner sphere has a radius R1 and uniform volume charge densityof ?; the outer sphere has a radius R2 and uniform surface chargedensity of s, and there is empty space between them. Note thatR1< R2. Use Gauss' Law to find the electric field in threeregions: a) Inside the inner sphere (r < R1), b) between them(R1 < r < R2), and c) outside the outer sphere (r > R2).Express your answers in terms of the charge density of each sphere(? and s ), the radii of the spheres (R1 and R2), and the distancer.
a solid conducting sphere of radius R has a charge Q on itssurface; the sphere is concentric with a larger, thick conductingspherical shell with inner radius R1, outer radius R2, and netcharge -Q. Find the electrostatic potential for(a) r > R2(b) R1 < r <R2(c) R < r < R1(d) r < RNeed explanation please!
