Unformatted text preview: negative charge and, thus, the leaves have a larger separation. (Or the you can imagine the rod pulling positive charge from the leaves with the same result.) If the leaves fall closer together, the electroscope has a positive charge. The negative rod pushes negative charges down onto the leaves, canceling part of the positive charge and, thus, the leaves have a smaller separtation. Exercise 2. The protons each carry one unit of positive charge, while the neutrons are neutral; that is, they are not charged. Therefore, the nucleus has 92 units of positive charge. We can go further and compute the charge in coulombs. In the Computing Box on page 427 or in the list of Physical Constants on the last page of the text, the size of the elementary charge is given. Therefore, ( 29 ( 29 19 17 92 1.6 10 C 1.47 10 C q ne= = =...
