Answer appropriately.

8) A negative charge, if free, tries to move A) in the direction of the electric field. B) from low potential to high potential. C) from high potential to low potential. D) away from infinity. E) toward infinity. 9) Gaussian surfaces A and B enclose the same positive charge +Q. The area of Gaussian surface A is three times larger than that of Gaussian surface B. The flux of electric field through Gaussian surface A is A) nine times larger than the flux of electric field through Gaussian surface B. B) unrelated to the flux of electric field through Gaussian surface B. C) equal to the flux of electric field through Gaussian surface B. D) three times smaller than the flux of electric field through Gaussian surface B. 10) If the electric field is in the positive x direction and has a magnitude given by E = Cx, where C is a constant, then the electric potential is given by V= A) 2Cx B) -2Cx C) Cx3/3 D) -CP3/3 E) -3Cx 2where Gumun where i'! he pond change ig at is renter Spherical Gaussian wirface el of the time sire. she encloses the charge hit a all ineed on A there are no offer theyes ride wither Gasian place, Compared to the electric flux through surface #1, Gaussian Gaussian surface #1 surface #2 Select one a greater. b, less, but not zero. c not enough information is given to decide. O e. the same. Next pageA Gaussian (closed) surface is drawn around a region of space. There are 25 field lines leaving the Gaussian surface, and 35 field lines entering the Gaussian surface. True or False: The region of space inside the Gaussian surface must contain some positive charge. True False
