Unformatted text preview: charges on the block itself is: 1. 0 N/C 2. 3200 N/C 3. 1152 N/C 4. 800 N/C 5. 1800 N/C Problem 4 In the diagram below, A and B are identical metal blocks. What is the final charge of block B? There are no external electric fields. 1. +6 nC 2. +3 nC 3. 0 nC 4.-3 nC 5.-6 nC 6. not enough information 3 Problem 5 You stand at location A, a distance d from the origin, and hold a small charged ball. You find that the electric force on the ball is 0.008 N. You move to location B, a distance 2d from the origin, and find the electric force on the ball to be 0.004 N. What object located at the origin might be the source of the field? 1. A point charge 2. A dipole 3. A uniformly charged rod 4. A uniformly charged ring 5. A uniformly charged disk 6. A capacitor 7. A uniformly charged hollow sphere 8. None of the above...
