Q1. A 78.0 kg person holds out his arms so that his hands are 1.70 m apart. Typically, a person's hand makes up about 1.00 5 of his or her body weight. For round numbers, we shall assume that all the weight of each hand is due to the calcium in the bones, and we shall treat the hands as point charges. One mole of Ca contains 40.18, and each atom has 20 protons and 20 electrons. Assume that only 1.00 percent of the positive charges in each hand were unbalanced by negative charge.
