Explanation of Solution

The atoms are mostly empty space mainly because of their composition. The atomic nucleus consists of proton and neutron, where both are very close to each other. The nucleus of this model atom is surrounded by a whirling cloud of orbiting electrons. Each orbit of electron and each orbiting electron has some space in between them. The mass of proton and neutron is very-very large compared to the mass of the electron, so most of the mass of atom lies in the nucleus and thus, the atom is mostly empty space.

(a) Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 13.0 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g/mol.
8 Two moving charged particles exert forces on each other because each creates a magnetic field that acts on the other. These two "Lorentz" forces are proportional to vix (2 xr) and 2 x (vi x-r), where is the vector between the particle positions. Show that these two forces are equal and opposite in accordance with Newton's third law if and only if rx (vi × 2) = 0.
6 The force = +3 + 2k acts at the point (1, 1, 1). Find the torque of the force about (a) (b) the point (2, -1, 5). Careful about the direction of ŕ between the two points. the line = 21-+5k+ (i-+2k)t. Note that the line goes through the point (2, -1, 5).
