Part E (i didnt know how to solve it)

Because the charges on the electron and proton have the same absolute value, atoms are electrically neutral. Suppose this were not precisely true, and the absolute value of the charge of the electron were less than the charge of the proton by 0.00100%.

(there are parts from A to E i solve all of them , but E i didnt know how to solve it )

Part A (solved)

Estimate what the net charge of the textbook of mass about 1.0 kg would be under these circumstances. Make any assumptions you feel are justified. (Hint: Most of the atoms in this textbook have equal numbers of electrons, protons, and neutrons.)

Express your answer using two significant figures.

Part B (solved)

What would be the magnitude of the electric force between two textbooks placed 7.0 m apart?

Express your answer using two significant figures.

4.2×1013

Part C (solved)

Would this force be attractive or repulsive?

Part D (solved)

Estimate what the acceleration of each book would be if the books were 7.0 m apart and there were no nonelectrical forces on them.

Express your answer using two significant figures.

Part E (i didnt know how to solve)

Discuss how the fact that ordinary matter is stable shows that the absolute values of the charges on the electron and proton must be identical to a very high level of accuracy.

Explanation / Answer

As it is evident from the calculations that the acceleration caused by the books of 1kg on each other when kept at a distance of 7 meters is extremely high, as high as 4.2*10^13 m/s2. This high level of acceleration is caused by merely an error of 0.001% in the determination of charges of particles. Even for a small error in the determination of charges will lead to astronomical changes in the reality. As such for a set of particles to be stable, the charges on the electrons and protons have to exactly same, if they are determined incorrect even by a very minute percentage, the system of particles or bodies become highly unstable.
