1. Two separated regions of a particular thundercloud have equal but opposite charges so that the cloud effectively acts as a parallel plate capacitor. See the diagram for more details. Assume the electric field, equal to 98.5 Volts/meter, is uniform between the two regions. The two regions shown in the cloud are a vertical distance of 600 meters apart.

the cloud are a vertical distance of 600 meters apart.
a. Sketch the uniform electric field between the two charged
regions.

b. What is the potential difference (voltage difference) between
the two oppositely charged regions shown in the cloud, 600
meters apart?
c. Within this uniform electric field region, what is the
potential difference (voltage difference) between two
locations separated by a vertical distance of only 2 meters?
d. If a free electron starts from rest at the negatively charged
region in the cloud, what will its speed be when it has
reached a point 2 meters above the negatively charged
region? (use energy conservation to solve this; ignore
gravitational effects, and ignore air resistance)
