Solved Imagine that two small steel balls (mass~5.6 g each)
What would the force magnitude be if we could remove them all? (Hint: steel is basically iron, and the iron. Imagine that two small steel balls (mass~5.6 g each) 0.10 m apart have the same positive charge. We observe that they repel each other with a force of 0.1 N ( a bit less than an ounce). What fraction of the electrons in each ball has ...
