Question 1 The gure shown above displays a cross section of a three dimensional closed surface with a at top and bottom surface above and below the plane of the page. If there is no ux through the top or bottom surface, the electric eld is everywhere parallel to the page and is uniform over each face of the surface, which of the following is true? Q There is no net charge enclosed. Q There is a negative net charge enclosed. Q There is a positive net charge enclosed. Question 2 Closed Surface e4 The figure above shows a hollow cavity within a neutral conductor of cross sectonal area 8.00 cm2 with a point charge of 0 = +5.70 nC inside. What is the net charge on the inside surface of the conductor? O Conductor is neutral throughout. O 5.70 no. O -5.70 mi)
