Multiplechoice questions may continue on the next column or page find all choices before answering. 001 10.0 points A (2 . 9 m by 2 . 9 m) square base pyramid with height of 3 . 82 m is placed in a vertical electric field of 59 . 3 N / C. b 2 . 9 m 3 . 82 m 59 . 3 N / C Find the total electric flux which goes out through the pyramids four slanted surfaces. Answer in units of N m 2 / C. 002 (part 1 of 2) 10.0 points A closed surface with dimensions a = b = . 373 m and c = 0 . 5222 m is located as in the figure. The electric field throughout the region is nonuniform and given by vector E = ( + x 2 ) where x is in meters, = 6 N / C, and = 3 N / (C m 2 ). E y x z a c b a What is the magnitude of the net charge enclosed by the surface? Answer in units of C. 003 (part 2 of 2) 10.0 points What is the sign of the charge enclosed in the surface?...
