THIS IS THE PREVIOUS QUESTION IT IS REFERRING TOO!! Your object has a mass of 35.6 kg. You separate an equal amount of protons and electrons into two boxes. You place the boxes at a distance of 80 m apart from one another. How much force attracts the two boxes to one another? Similar situation to the previous question, but now the object s mass is 60.0 kg and you initially put the boxes of protons and electrons 24 m apart. Now you want to take the two boxes and move them farther apart, to a new distance of 45 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? 1.44E+27 J 2.88E+27 J 5.76E+27 J 7.20E+26 J
A proton and electron are separated by a distance of 8.1x10-8 m. What is the force, in N, between them? Express your answer in scientific notation. Remember, the charge on a proton is +1.6 x 10-19 C, charge on an electron is -1.6 x 10-19 C, and the electric constant K = 9 x 109 Nm2/C2
Q3. Two protons in an atomic nucleus are typically sepa- rated by a distance of 2.3*10^-15 m. The electric repulsive force between the protons is huge, but the attractive nuclear force is even stronger and keeps the nucleus from bursting apart. What is the magnitude of the electric force between two protons separated by 2.3*10^-15 m (if you know that the charge of proton = 1.6*10-19)?
