Question 1, chap 22, sect 1. part 1 of 1 10 points A plastic rod is rubbed against a wool shirt, thereby acquiring a charge of -4 C. The charge on an electron is -19 -1.6 10 C. How many electrons are transferred from the wool shirt to the plastic rod? Question 2, chap 22, sect 2. part 1 of 1 10 points A particle of mass 26 g and charge 44 C is released from rest when it is 83 cm from a second particle of charge -22 C. Determine the magnitude of the initial acceleration of the 26 g particle. Answer in units of m/s2 .
