A solid conducting sphere of radius a has a net positive charge 2q a conducting spherical shell of inner radius b and outer radius c is connected with the solid sphere and has a net charge -q find surface charge density on the inner and outer surface of the spherical shell?
Answers
Answer:
Explanation1.) A region of space contains an electric field E = E1i + E2j where E1 and E2 are positive constants. A frame whose corners are located at (x, y, z) = (a/2, 0, a/2), (-a/2, 0,-a/2), (a/2, 0,-a/2), and (-a/2, 0, a/2). What is the magnitude of the electric flux through the frame?
2.) A solid non-conducting sphere of radius R carries a charge Q1 distributed uniformly. The sphere is surrounded by a concentric spherical shell of inner radius Ra and outer radius Rb. The shell carries a total charge Q2 distributed uniformly in its volume. What is the net electric field at a radial distance r such that R < r < Ra?
3.) An infinitely long cylinder of radius R = 2 cm carries a uniform charge density ρ = 18 μC/m3. Calculate the electric field at distance r = 1 cm from the axis of the cylinder.
4.) Two parallel flat planes of positive charge are separated by a distance d. Plane #1 has charge density and plane #2 has a charge density σ2. σ1> σ2. (a) In the region between the planes, the magnitude of the electric field is (b) In the region outside the planes the magnitude of the electric field is:
