CASE STUDY Concept Exercise 27.1 (page 829), we ignored air resistance acting on the ring launched by the experimenters in the case study. How would including air resistance change your answer to the question about the size of the spring? Does air resistance require that more, less, or the same amount of electric potential energy be stored in the spring? Explain your answers.
If you have ever tried to hang a picture or a mirror, you know it can be difficult to locate a wooden stud in which to anchor your nail or screw. A carpenters stud finder is a capacitor with its plates arranged side by side instead of facing each other as shown in Figure 25.14. When the device is moved over a stud, does the capacitance (a) increase or (b) decrease?
Many computer keyboard buttons are constructed of capacitors as shown in Figure 25.3. When a key is pushed down, the soft insulator between the movable plate and the fixed plate is compressed. When the key is pressed, what happens to the capacitance? (a) It increases. (b) It decreases. (c) It changes in a way you cannot determine because the electric circuit connected to the keyboard button may cause a change in V.

Solve the following problem sets, use GRESA, final answers should be in two decimal places. A capacitor of 3.23µF has an area of 6.35mm^2. Determine the separation distance between the two plates.

I only want 4 and 5. I pasted the whole question as a reference only. Two parallel plates, each having area A = 3085cm2 are connected to the terminals of a battery of voltage Vb = 6 V as shown. The plates are separated by a distance d = 0.49cm. You may assume (contrary to the drawing) that the separation between the plates is small compared to a linear dimension of the plate. 1) What is C, the capacitance of this parallel plate capacitor? 2) What is Q, the charge stored on the top plate of the this capacitor?. 3) A dielectric having dielectric constant κ = 3.4 is now inserted in between the plates of the capacitor as shown. The dielectric has area A = 3085 cm2and thickness equal to half of the separation (= 0.245 cm) . What is the charge on the top plate of this capacitor? 4) What is U, the energy stored in this capacitor? 5) The battery is now disconnected from the capacitor and then the dielectric is withdrawn. What is V, the voltage across the capacitor?
