A conductive "hollow" sphere has a total charge -2Q. A charging point + Q is in the center. Determine the total load on the outer surface. a. -Q b. +Q c. -3Q d.+2Q

3. A hollow, conducting sphere is initially uncharged. A positive charge, +9₁, is placed inside the sphere, as shown in the figure below. Then, a second positive charge, +q2, is placed near the sphere but outside it. Which of the following statements describes the net electric force on each charge? +9₂ A. There is a net electric force on +91 but not on +92. B. Both charges are acted on by a net electric force with the same magnitude and in the same direction. C. Both charges are acted on by a net electric force with the same magnitude but in opposite directions. D. There is a net electric force on +q2 but not on +9₁.

A point charge gives rise to an electric field with magnitude 4 N/C at a distance of 9 m. If the distance is increased to 45 m, then what will be the new magnitude of the electric field?    N/C

An electric dipole is enclosed by a Gaussian surface. The net electric flux through the entire surface is what? a. not equal to zero since there charges that are enclosed b. not equal to zero because the Gauss's law states that the total flux is equal to the total charge c. equal to zero because the flux produced by the dipole cancels each other d. equal to zero because the charge enclosed is also zero
