- A hydrogen atom is made up of a proton of charge +Q = −1.60×10-19 C and an electron of charge −Q = −1.60×10−19 C. The proton may be regarded as a point charge at r = 0, the center of the atom. The motion of the electron causes its charge to be "smeared out" into a spherical distribution around the proton (Figure 1), so that the electron is equivalent to a charge per unit volume of ρ(r)=−(Q/πa03)e−2r/a0, where a0 = 5.29×10-11m is called the Bohr radius.

- Because the charges on the electron and proton have the same absolute value, atoms are electrically neutral. Suppose that this is not precisely true, and the absolute value of the charge of the electron is less than the charge of the proton by 0.00100%. Estimate what the net charge of this textbook would be under these circumstances. Make any assumptions you feel are justified, but state clearly what they are. (Hint: Most of the atoms in this textbook have equal numbers of electrons, protons, and neutrons.) What would be the magnitude of the electric force between two textbooks placed 5.0 m apart? Would this force be attractive or repulsive? 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.The electric field vector is given by E=[0.2, –0.6, 0.3] V/m and Area vector points to A=[–4, 3, -5] m^2.
