Help!! I really don't know how to resolve it Two identical small electrified balls are not repelled. After being brought into contact and fixed at a distance of 1.25 times greater, their intersecting force did not change. What was the load, the first ball, if the second had a load equal to 1μC? The answer should be: 4μC; 0.25μC;

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object
