(i) An isolated cubical conductor has an excess charge of 5.30 μC placed on its surface. Inside the conductor is a cavity, within which is a point charge of 4.10 μC. How many excess electrons are on the wall of the cavity? (ii) Calculate the total electric flux that would pass through an irregularly shaped Gaussian surface drawn around the conductor in the previous problem.
Three point charges are located near a spherical Gaussian surface of radius 12.5 cm. One charge (+3Q =11.4 μC) is inside the sphere, and the others (charge +Q =3.8 μC) are a distance 4.16666666666667 cm outside the surface. What is the total (net) electric flux through the Gaussian surface?
How many excess electrons must be added to an isolated spherical conductor 26.0 cm in diameter to produce an electric field of magnitude 1250 N/C just outside the surface?
5. Consider a point charge at the center of a spherical Gaussian surface. Explain why of why not the electric flux changed (a) if the Gaussian surface is replace with a cube having the same volume as the sphere, (b) if the cube has 1/2 the volume of the sphere, (c) if the charge is moved off-center from the original sphere yet remains inside, (d) if the charge is moved just outside the sphere, (e) if a second charge is...
