A silk scarf and a glass rod are rubbed together for one minute. Once completed, the rod is said to be negatively charged. 1. The electrons will travel from the (scarf/rod) to the (scarf/rod). 2. The (scarf/rod) has a higher electron affinity. 3. The electrical force between scarf and the rod two charges would be (attractive/repulsive). 4. Explain your responses to problems #1-3 below. A physics student then takes the negatively charged rod and witnesses that when AFTER placed next to a neutral piece of paper, the paper and the rod attract. - - - - - 5. What happens within the paper that causes the objects to stick together? Draw in the charges on the paper and generate a written explanation. Charge A is -1.5x10 C, Charge Bis + 2.35 x 10* C, and Charge C is +7.0 x 10" C. All charges are on a friction negligible surface. 0.25m B 0.25m A C 6.
