7. When the terminals of a battery are connected to two parallel conducting plates with a small gap between them, the resulting charges on the plates produce a nearly uniform electric field between the plates. If the plates are 1.0 cm apart and are connected to a 100-volt battery (as shown in Figure below), the field is vertically upward and has magnitude E = 1.00 x104 N/C. (a) if an electron (charge -e= -1.60 x10⁹ C), mass m= 9.11 x10 -³¹ kg) is released from rest at the upper plate, what is its acceleration? (b) What speed and kinetic energy does it acquire while traveling 1.0 cm to the lower plate? (c) How long does it take to travel this distance? 100 V 48 The thin arrows represent the uniform electric field. + + F = -eE + + + x 1.0 cm

You have likely experienced "static shock" recently. The magnitude of charge transferred when you walk across a carpet, reach out and touch a doorknob, and unintentionally give yourself that static shock is around 2.98 nC (nC stands for nano-Coulomb). In units of Giga-electrons, about how many electrons are transferred when you experience static shock? Note: it is understood that the unit of your answer is in billions of electrons (hence Giga-electrons), however do not explicitly include units in your answer.
6. Two identical spheres with mass m are hung from silk threads of length L as shown in Fig. Each sphere has the same charge q1=92=9. L L mass m charge 91 mass m charge 92 The radius of each sphere is very small compared to the distance between the spheres, so they may be treated as point charges. Show that if the angle is small, the equilibrium separation between the spheres is d = 2πε mg
A proton Q = +e and an electron Q = -e are in a constant electric field created by oppositely charged plates. You release the proton from near the positive plate and the electron from near the negative plate. Which feels the larger electric force? O The electron. O The proton. O Neither-there is no force. O The magnitude of the force is the same for both and in the same direction. O The magnitude of the force is the same for both but in opposite directions.

Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. Imagine adding electrons to the pin until the negative charge has the very large value 1.00 mC. How many electrons are added for every 109 electrons already present?
