Question
C Positively charged. The field is in the opposite direction from the force on the test charge. (6) Which describes the electric flux through a section of a closed surface? A It is a vector that is directed outward through the section. B It is a vector that is tangent to the section. C It is a scalar. (7) Three capacitors, each of capacitance C, are connected to a battery. What is Coy of the three capacitors if they are connected to a battery in series with one another? A C B 3C C C/3 (8) In the figure, two particles of charge -q are arranged symmetrically about the y axis; each produces an electric field at point P on that axis. Are the magnitudes of the fields at P equal? Yes B No (9) in cross section, aplastic, spherical shell with uniform charge Q-16e R-10 cm. A particle with charge q-+5e , e-1.6x 10'"C is at the center. What is the electric field at point Pl (r-6 cm) P2 (r-12 cm) q PI P2Explanation / Answer
6) C. flux is scaler product of area and electric field.
7) C. for series combination, 1/Ceq = 1/C + 1/C + 1/C, Ceq = C/3
