QUESTION 1: A +1.80 μC point charge is sitting at the origin.
A: What is the radial distance between the 500 V equipotential surface and the 1000 V surface?
Express your answer in meters to three significant figures.
B: What is the distance between the 1000 V surface and the 1500 V surface?
Express your answer in meters to three significant figures.
C: Explain why the answers to Part A and Part B are not the same.
QUESTION 2: Here we will apply the equation C=QVab=ϵ0Ad to a parallel-plate capacitor that has a capacitance of 1.0 F and a plate separation of 1.0 mm. What is the area of the plates?
PART A: What is the area of each plate of a parallel-plate air capacitor that has a capacitance of 2.0pF=2.0×10−12F if the separation between the plates is 1.0 mm?
Express your answer in meters squared to two significant figures.
PART B: If the plates are square, what is the length of each side?
Express your answer in millimeters to two significant figures.
QUESTION 3: You find that if you place charges of ± 1.10 μC on two separated metal objects, the potential difference between them is 11.1 V . What is their capacitance?
QUESTION 4: A capacitor has a capacitance of 7.38 μF . What amount of excess charge must be placed on each of its plates to make the potential difference between the plates equal to 26.0 V ?
