5. The N pole faces of two cylindrical neodynium magnets having a radius of 0.5 cm and a length of 20 cm are brought together so that their faces are parallel and there is a small gap between them. The magnetic surface charge density on each pole face is 2 x 10° Cm's. (a) What is the force between the magnets in the limit in which the gap goes to zero? -Assume that the magnets are much longer than shown in the figure below, so that you only need to concern yourself with the repulsion between N and N. (b) What is the force between the magnets when they are separated by 0.5 m? At this separation you can approximate the four pole faces as point-charges.

Ignoring trace elements, a typical elemental composition (by mass) of the human body is as follows: 10.5 % H 66.3 % O 19.9 % C 3.3 % N Use these percentages, the molar mass values, Avogadro's number, and the atomic numbers to determine the total number of electrons (and protons) in a 73-kg human body (160 pounds). If these electrons and protons were placed 100 m apart (the distance of approximately one football field), then what would be the force of electrical attraction between them.
