QUESTION 1Consider an object of mass 76.4 kg. Assume that it s made up of equal numbers of protons, neutrons, and electrons. How many protons does this object contain? 4.58E+28 9.16E+28 1.15E+28 2.29E+28QUESTION 2This time your object has a mass of 12.3 kg. 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? 5.89E+08 C 1.18E+09 C 2.36E+09 C 2.95E+08 CQUESTION 3This time your object has a mass of 62.7 kg. You separate the protons and electrons into two boxes like in the previous question. You place the boxes at a distance of 68 m apart from one another. How much force attracts the two boxes to one another? 1.75E+25 N 3.50E+25 N 7.00E+25 N 8.75E+24 NQUESTION 4Similar situation to the previous question, but now the object s mass is 40.4 kg and you initially put the boxes of protons and electrons 76 m apart. Now you want to take the two boxes and move them farther apart, to a new distance of 174 m apart. How much work (that is, energy) would you have to expend to pull the boxes that much farther apart, fighting against the electrostatic attraction between them? 2.50E+26 J 5.00E+26 J 1.00E+27 J 1.25E+26 JQUESTION 5Your object has mass 79.9 kg, and you ve separated the boxes of protons and electrons by a distance of 59 m. If you were to release the clump of protons from their box, how much acceleration would the clump of protons undergo due to its attraction to the clump of electrons in the other box? 1.89E+24 m/s^2 3.78E+24 m/s^2 4.74E+23 m/s^2 9.47E+23 m/s^2QUESTION 6The 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 12 protons on positive x-axis, at x = 2.7 Angstroms. How much work did it take you to bring this nucleus in from 1 m away? 76.7 eV 54.3 eV 63.9 eV 44.7 eVQUESTION 7This time you put a nucleus with 8 protons on the x-axis at x = 7.1 Angstroms. There will be a place on the x-axis where the total electric field is zero. At what value of x does this occur? 0.93 Angstroms 0.47 Angstroms -3.88 Angstroms -1.55 AngstromsQUESTION 8Now you have a nucleus with 5 protons, placed at x = 2.7 Angstroms. What what TWO values of x (along the x-axis) will the total electrostatic potential V be equal to zero? 0.54 Angstroms and -0.18 Angstroms -0.68 Angstroms and 0.45 Angstroms 0.68 Angstroms and -0.45 Angstroms -0.54 Angstroms and 0.18 AngstromsQUESTION 9Now you have a nucleus with 18 protons at x = 3.0 Angstroms on the x-axis. What is the value of the electrostatic potential V at a point on the positive y-axis, at y = 4.3 Angstroms? 46.0 V -3.3 V 49.4 V 27.6 VQUESTION 10Now you have a nucleus with 16 protons at x = 5.0 Angstroms on the x-axis. How much work would it take to bring in ANOTHER nucleus with 5 protons from 1 m away and place it at y = 5.2 Angstroms on the y-axis? 87.4 eV 145.7 eV -13.8 eV 159.5 eV
