Consider an object has a mass of 43.4 kg. You separate the protons and electrons of the object into two boxes. You take all the protons out of the object and stuff them into a box and also take all the electrons out of the object and stuff them into a second box. You initially put the boxes of protons and electrons 45 m apart. Now you want to take the two boxes and move them farther apart, to a new distance of 81 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? 1.92E+26 J 3.84E+26 J 7.68E+26 J 1.54E+27 J

Question
Consider an object has a mass of 43.4 kg. You separate the protons and electrons of the object into two boxes. You take all the protons out of the object and stuff them into a box and also take all the electrons out of the object and stuff them into a second box.
You initially put the boxes of protons and electrons 45 m apart. Now you want to take the two boxes and move them farther apart, to a new distance of 81 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?

Expert Solution
Step 1
Given that,
the mass of an object is
The initial separation between the proton and electron box is
The final separation between the proton and electron box is
Since the mass of the electron is
the mass of the proton is
the mass of the neutron is
Considering the object has an equal number of electrons, protons, and neutrons, then
Putting the values
Step by step
