QUESTION 1Consider an object of mass 76.4 kg. Assume that it s made up of equal numbers of protons, neutrons, and electrons.

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.

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.

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
