Inez uses hairspray on her hair each morning before going to school. The spray spreads out before reaching her hair partly because of the electrostatic charge on the hairspray droplets. If two drops of hairspray repel each other with a force of 9.0 x 10-° N at a distance of 0.070 cm, what is the charge on each of the equally charged drops of hairspray? O 7*10^-11 C O 7*10^-13 C O 7*10^-22 C 4.9*10^-25 C
When a positively charged rod is brought near a conducting sphere, negative charge migrates toward the side of the sphere close to the rod so that net positive charge is left on the other side of the sphere. The method by which charge separation is created on the conducting sphere is known as a. charging by convection. O b. charging by polarization. C. charging by reflection. d. charging by friction. e. charging by induction.
You can give a rubber rod a negative charge by rubbing the rod with wool. What happens to the charge of the wool? The wool becomes neutrally charged because it gives up electrons to the rubber rod. The wool becomes negatively charged because it gives up electrons to the rubber rod. The wool becomes positively charged because it gives up electrons to the rubber rod.
2. Consider an object of mass 77.1 kg. Assume that it is made up of equal numbers of protons, neutrons, and electrons. Now imagine taking all the protons out of the object and stuffing them into a box. Also take all the electrons out of the object and stuff them in a second box. How much charge is contained in the box with all the protons? 7.38E+09 C 1.48E+10 C 1.85E+09 C 3.69E+09 C

I am struggling with understanding this review question, I have changed the numbers to practice the problem again later on. If I have a 2.5 gram copper penny and it has a charge of -2.0×10-9C (i) How many excess electrons are on the penny? (ii) By what percent do the excess electrons change the mass of the penny? If the penny's mass remains the same but the charge changes to 4.0×10-9C (iii) How many electrons have been removed from the penny? (iv) If only one electron is removed from the atom, what percent of the atoms are ionized by this charging process? Any help would be greatly appreciated :)

40. Two metal spheres are resting on insulating stands. Sphere A has a net positive charge, and sphere B is neutral. The two spheres are brought into contact with each other, and then are separated. Which describes the transfer of charge between Sphere A and B, and the final result of net charges after they are separated? A.Positive charges move from Sphere A onto Sphere B, resulting in both Sphere A and Sphere B having net positive charge. B. Positive charges move from Sphere B onto Sphere A, resulting in both Sphere A and Sphere B having net positive charge. C.Negative charges move from Sphere A onto Sphere B, resulting in both Sphere A and Sphere B having net negative charge. D.Negative charges move from Sphere B onto Sphere A, resulting in both Sphere A and Sphere B having net positive charge.
