Solve the following physics problems, thank you. Happy new year!
1. The parallel plates of an air capacitor are separated by 2.24 mm. Each plate carries a charge of 6.50 nC. The magnitude of the electric field of the plates is 4.75 x 105 V/m. Find the (a) potential difference between the plates, (b) capacitance, and (c) area of the plate.
2. Two capacitors with 2.0 F and 3.0 F capacitance, respectively, are connected in parallel. The combination is connected to a 100 V line. Find the (a) total capacitance, (b) charge stored in each capacitor, and (c) potential difference across each capacitor.
3. A parallel plate capacitor consists of two rectangular plates, each with an area of 4.5 cm2 and are separated from each other by a 2.00 mm thick dielectric with a dielectric constant of 5.26. The capacitor is connected to a 12.0 V battery. How much energy is stored in the capacitor?
In the Millikan oil-drop experiment, an atomizer (a sprayer with a fine nozzle) is used to introduce many tiny droplets of oil between two oppositely charged parallel metal plates.
