- Find some small light pieces of paper and you'll notice in the paper experiments that as you bring the comb up to the paper bits or a lightweight sheet it will move. Almost any small material -- bread crumbs work -- will be attracted, not repelled. Given that the comb is already charged, which explanation is the best? Since the comb is negative, electrons on the paper are repelled and there is net positive charge closest to the comb. That creates net force in the direction of the comb and if it is light enough, the bits experience a net upward force that accelerates them toward the comb. Paper is always negatively charged. The paper may have either positive or negative charge randomly, some bits will go toward the comb, some will be repelled. Paper is always positively charged.Object A and Object B are neutral and were rubbed against each other with the aim of facilitating charging by friction. In the process Object A gains 100 quadrillion (1000 trillion) electrons. Which of the following is/are valid? Select all correct options. a. Object B has a charge of -0.016020C b. Object B has a charge of 0.190200C c. Object A has a charge of 0.016020C d. Object A has a charge of -0.052866C e. Object A has a charge of -0.016020C f. Object B has a charge of 0.016020C g. Object A has a charge of -8.602000C h. Object B has a charge of 0.113742CIn Thomson’s model, an atom is a positively charged spherical material in which negatively charged electrons are embedded like chocolate chips on a ball of cookie dough. Consider such an atom, made up of a uniformly charged sphere with charge +e and radius R and a point charge with mass m and charge −e. a. Locate the position of electrostatic equilibrium for the electron inside the sphere. b. Assume further that the sphere has little or no resistance to the electron’s mo- tion. If the electron is displaced from equilibrium by a distance less than R, show that the resulting motion of the electron would be simple harmonic. c. If the electron was displaced from equilibrium by a distance greater than R, would the electron oscillate? Would its motion be simple harmonic?
- Please send me answer within 10 min! I will rate you good for sure!! Please provide explanation!!6. The next 5 questions all have to do with the diagram shown, on which I have placed an electron at the origin. The grid spacing is 1 Angstrom per small square. Now place an atomic nucleus with 8 protons on positive x-axis, at x = 7.6 Angstroms. How much work did it take you to bring this nucleus in from 1 m away? 22.7 eV 11.4 eV 15.1 eV 7.6 eVThe electroscope is an apparatus used to detect electric charge. The electroscope consists of a plate, a support and thin metal foil that is free to deflect all made of metal. After rubbing a balloon on your sleeve, the negatively charged balloon is brought near to the metallic plate of an electroscope. As a result, the foil of the electroscope deflects. As the balloon approaches the electroscope, what is the net charge on the electroscope? Negative Positive Neutral Cannot be determined
- Suppose a swarm of bees flies through a thunderstorm and they become charged to –10.0 µC each. If there are 5,000 bees in the hive, what is the total electric flux through the walls of the hive? a. b. The Hatfields and McCoys have a historic feud, and now they have physics degrees. Using the figure below, if the bees fly straight up out of the hive and Mr. Hatfield would like to deflect the bees toward Mr. McCoy, in what direction should he apply a magnetic field (into the page or out of the page)? Vbees "leaving x-axis Om 100m 200m Mr. Hatfield hive Mr. McCoy If the bees fly straight up at 0.5 m/s, and a 50 µT magnetic field is applied in the direction you indicated in part (b), what is the magnetic force that the bees experience? (Both strength and direction.) d. When the bees return to the hive they fly straight down into it. If the magnetic field is still applied in the direction of your answer to part (b), in what direction are the bees deflected?This question has to do with the diagram shown, on which I have placed an electron at the origin.
