Lesson 2.1 Homework 1. What is the total positive charge contained in 1.0 kg of hydrogen gas? 2. How many protons are there in 1.0 C of positive charge? 3. Two charged particle exert a force of 4.2 × 10 -2 N on each other. They are moved towards each other so that the distance between them now one-eighth of the original value. What is the force they exert on each other now? 4. Two charged balls are 15 cm apart. They are moved away from each other so that the force is now one-third of the original value. How far apart are they now? 5. Three point charges each carrying a charge of 11.0 μ C are located at the corners of an equilateral triangle of side 15.0 cm. Calculate the magnitude and direction of the force on each charge. 6. You and a friend each have mass 60 kg and each are holding a 1.0 c charge. At what distance from each other is the magnitude of the electrical force on the charges equal to your weight on the surface of the earth? 7. Two equal point-like masses, each carrying positive charge q, are suspended from a common point by threads of equal length l. The
