Exam Name___________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) What is the electric field strength if the flux through a 2.0 m by 1.0 m rectangular surface is 156.0 N œ m 2 /C, if the electric field is uniform, and if the normal to the surface is at an angle of p /3 radians with respect to the direction of the field? A) 39 N/C B) 90 N/C C) 78 N/C D) 156.0 N/C 2) A charge of 9.0 x 10 -6 m C is located inside a sphere. What is the flux through the sphere? A) 0.25 p N œ m 2 /C B) 80 N œ m 2 /C C) It cannot be determined if the radius is unknown. D) 1.0 N œ m 2 /C Figure 22.2 Two point charges, Q 1 = -1.0 m C and Q 2 = +2.0 m C, are placed as shown. 3) In Figure 22.2, the number of excess electrons in charge Q 1 is closest to: A) 6 x 10 11 B) 6 x 10 12 C) 2 x 10 11 D) 2 x 10 13 E) 2 x 10 12 4) In Figure 22.2, the x-component of the electric field, at the origin O, is closest to: A) -3600 N/C B) +2700 N/C C) -9000 N/C
