How do I solve this?

Question 1 Question: Not yet answered Part 1) Marked out of 1.00 Flag question When two materials are rubbed together the friction will often cause one to lose electrons while the other gains elec some positive and which become negative. It can be written as: TRIBO ELECTRIC SERIES MOST POSITIVE Glass Silk Wool Fur Wood Rubbe Silicon MOST NEGATIVE Ebonite When Ember (a cat, covered in fur) is rubbed with a balloon made from rubber which of the following statements is true? Ember becomes positive because it has lost electrons. Ember becomes negative as she has gaine ectrons, the balloon becomes positive because it has lost electrons. Ember becomes posi se it has gained electrons. Ember becomes negative as she has lost electrons, the balloon becomes positive because it has gained electrons. Part 2) In another experiment, a small, initially neutral, polystyrene bead is charged to q = -2.92 /C. Calculate the number of electrons that are gained/lost during this process. Enter a positive number into the box. electrons are (No answer given) * Part 3) This small polystyrene bead is placed at the origin. Calculate the electric field due to the polystyrene bead at the point (0.196, 0, 0)m. E = i + 3 + K N/C Next page
