6. What is the neth the torus le, dohnushape) of the figure ? Assume that Q-200nC and q-9.0nC. insid 7. The electric field strength just above one face of a copper penny is 1890 N/C. What is the surface charge density on this face of the penny? 8. A thin, horizontal, 10-cm-diameter copper plate is charged to -3.0 nC. Assume that the electrons are uniformly distributed on the surface. What is the strength of the electric field 0.1 mm above the center of the top surface of the plate? What is the direction of the electric field 0.1 mm above the center of the top surface of the plate? What is the strength of the electric field at the plate's center of mass? 9. A s pherical cavity is hollowed out of the interior of a neutral conducting sphere. At the center of the cavity is a point charge, of positive charge q. What is the total surface charge q on the interior surface of the conductor (i.e., on the wall of the cavity)? What is the total surface charge Ger on the exterior surface of the conductor? What is the magnitude Eme of the electric field inside the cavity as a function of the distance r from the point charge? What is the electric field Eet outside the conductor?Explanation / Answer
Q6.
Since Q is outside, it won't add to net flux.
q is inside the torus.
So From Gauss' Law, net flux = E.dS
= q/0
Net flux = (-9*10^-9)/(8.85*10^-12)
= -1017 Nm^2/C
