Unformatted text preview: AP Electrostatics Clicker Questions Question 1 The figure above shows a spherical distribution of charge of radius R and constant charge density ρ . Which of the following graphs best represents the electric field strength E as a function of the distance r from the center of the sphere? Question 2 • The electric field of two long coaxial cylinders is represented by lines of force as shown above. The charge on the inner cylinder is +Q. The charge on the outer cylinder is • (A) +3Q (B) +Q (C) 0 (D) ‑ Q (E) ‑3 Q Question 3 The electric field E just outside the surface of a charged conductor is (A) directed perpendicular to the surface (B) directed parallel to the surface (C) independent of the surface charge density (D) zero (E) infinite Question 4 Two positive charges of magnitude q are each a distance d from the origin A of a coordinate system as shown above. At which of the following points is the electric field least in magnitude? (A) A (B) B (C) C (D) D (E) E Question 5 A closed surface, in the shape of a cube of side a, is oriented as shown above in a region where there is a constant electric field of magnitude E parallel to the x‑axis. The total electric flux through the cubical surface is (A) ‑Ea 2 (B) zero (C) Ea 2 (D) 2Ea 2 (E) 6Ea 2 Question 6 The net electric flux through a closed surface is A) infinite only if there are no charges enclosed by...
