Unformatted text preview: Consider a parallel-plate capacitor whose plates are very large compared to their distance of separation d. The plates are given equal and opposite charges. The field between the plates 1. falls like 1/d 2. 2. is positive near the positive plate and negative near the negative plate. 3. is approximately constant and points from positive to negative plate. 4. is approximately constant and points from negative to positive plate. 5/10/10 Physics 122 (2 pts) 3 Consider a parallel-plate capacitor whose plates are very large compared to their distance of separation d. The plates are given equal and opposite charges. The potential between the plates 1. falls like 1/x. 2. falls linearly (like –kx+c). 3. is close to being constant. 4. cannot be determined from the information given. (2 pts) 5/10/10 Physics 122 4 Consider a simple parallel-plate capacitor whose plates are given equal and opposite charges by being connected to a battery. Suppose the plates are disconnected from the battery are pulled farther apart . The electrostatic energy stored in the capacitor is 1. greater than 2. the same as 3. smaller than before the plates were pulled apart. (3 pts) 5/10/10 Physics 122 5 Consider a simple parallel-plate capacitor whose plates are given equal and opposite charges by being connected to a battery. Suppose the plates are pulled farther apart while still connected to the battery. The electrostatic energy stored in the capacitor is 1. greater than 2. the same as 3. smaller than before the plates were pulled apart. (3 pts) 5/10/10 Physics 122 6 ...
