Textbook Question
Chapter 22, Problem 4P
Nobel laureate Richard Feynman (1918–1088) once said that if two persons stood at arm’s length from each other and each person had 1% more electrons than protons, the force of repulsion between them would be enough to lift a “weight” equal to that of the entire Earth. Carry out an order-of-magnitude calculation to substantiate this assertion.

Protons in the nucleus of atoms can be within a few femtometers of one another (femto= 10-¹5).
If two protons are 3.0 femtometers apart then how much force does each proton exert on the
other? Is the force repulsive or attractive? Compare that to the force between the proton and
electron in Example 16-1.
In this experiment oil drops are suspended in a vertical electric field against the gravitational force to measure their charge. If the mass of a negatively charged drop suspended in an electric field of 1.76 ✕ 10−4 N/C strength is 2.299 ✕ 10−20 g, find the number of excess electrons in the drop.
