What if one charge has twice the magnitude of the other? 1. The smaller charge will exert a force four times as strong. 2. The forces will be equal. 3. The bigger charge will exert a force four times as strong. 4. The smaller charge will exert a force twice as strong. 5. The bigger charge will exert a force twice as strong. Positive Charge Distribution 002 10.0 points A solid conducting sphere is given a positive charge Q . How is the charge Q distributed in or on the sphere? 1. It is uniformly distributed on the surface of the sphere only. 2. It is concentrated at the center of the sphere. 3. Its density decreases radially outward from the center. 4. It is uniformly distributed throughout the sphere. 5. Its density increases radially outward from the center. One Joule of Work 003 10.0 points One joule of work is needed to move one coulomb of charge from one point to another with no change in velocity.
