1. Why is it important to avoid sharp edges or points on conductors used in high-voltage equipment? Relate the electric potential equation with electric ield to explain your answer. 2. You may have heard that one of the safer places to pe during a lightning storm is inside a car. Why would his be the case? Use the Gauss's Law to explain your answer. Use drawing or diagram to illustrate the electric field.

Electric fields are caused by both point charges and by parallel plates with a potential difference across them. Describe the difference between the electric field caused by a point charge and the electric field between parallel plates. Your answer should include a diagram of each type of field and reference to electric field strength. c) Derive a mathematical relation between Electric Field Strength (E) and Potential difference (V). d) Calculate the Electric Field Strength between the plates.

A particle accelerator is used to accelerate particles... (obviously right?). a) Draw a diagram that would represent an electron, starting from rest, and passing between two plates with a potential difference of 5.3 x 10^5 V and the plates separated 12cm apart. (Include SIGNS on plates), accelerating. b) How fast would the electron be traveling once it gets to the plate? c) What would be the magnitude of the electric field strength? d) What would be the acceleration of the electron?

22. How much charge in coulombs is stored by a 50-μF capacitor         with 20 V across its plates?        A. 100 μC            B. 2.5 μC              C. 1 mC              D. 1 μC

A negative test charge is placed in a region of positive source. Which of the following statements is true? a. The electric potential energy increases as it moves in the direction of the field. b. The electric potential energy increases as it moves in the direction opposite the electric field. c. The electric potential energy decreases as it moves in the direction of the field.
