wo foam blocks, each with a charge of 8 microcoulombs (1 µC = 10-6 C), are both held in place 8 cm apart in the east-west direction. A foam ball with a charge 38 µC is placed 55 cm north of the foam block on the west side. Then, the ball is released, and it moves as a result of the electrostatic force produced in this system. What is the strength of the electric field (magnitude and direction) exerted on the ball by the closer block?

In this example, we will analyze the motion of an electron that is released in an electric field. The terminals of a 100 V battery are connected to two large, parallel, horizontal plates 1.0 cm apart. The resulting charges on the plates produce an electric field E in the region between the plates that is very nearly uniform and has magnitude E = 3.0×104 N/C. Suppose the lower plate has positive charge, so that the electric field is vertically upward, as shown in (Figure 1). (The thin pink arrows represent the electric field.) If an electron is released from rest at the upper plate, what is its speed just before it reaches the lower plate? How much time is required for it to reach the lower plate?
