Question 1 10 N/C 10 N/C 10 N/C The figure shown above displays a cross section of a three-dimensional closed surface with a flat top and bottom surface above and below the plane of the page. If there is no flux through the top or bottom surface, the electric field is everywhere parallel to the page and is uniform over each face of the surface, which of the following is true? There is no net charge enclosed. There is a negative net charge enclosed. There is a positive net charge enclosed. Question 2 Closed Surface Q The figure above shows a hollow cavity within a neutral conductor of cross sectional area 5.00 cm² with a point charge of Q = +7.20 nC inside. What is the net charge on the inside surface of the conductor? 7.20 nC -7.20 nC Conductor is neutral throughout. Question 3 + 3q + q - q - 3q A B C D E What is the electric flux through surface E of the figure provided? -4q/?? +3q/?? +4q/?? 0 Question 4 Wire The figure provided shows a metal sphere hanging by an insulating thread within a hollow conducting sphere. A conducting wire extends from the metal sphere through a small hole in the hollow sphere, but without making contact with the metal sphere. A charged rod is then used to transfer positive charge to the protruding wire. After the charged rod has touched the wire and been removed, what is the charge of the inner surface of the hollow sphere? Neutral Positive Negative
