Answer to Question #200619 in Physics for Delta

Question

1.A plane-parallel capacitor has circular plates of radius r = 10 cm, separated by a distance d =1 mm. How much charge is stored on each plate when their electric potential difference has the value V = 100 V?

2. How much charge is stored in a capacitor consisting of two concentric spheres of radii 30 and 31 cm if the potential difference is 500 V?

3. What is the capacitance of the Earth, viewed as an isolated conducting sphere of radius 6370 km?

4. The space between the conductors of a long coaxial cable, used to transmit TV signals, has an inner radius a = 0.15 mm and an outer radius b = 2.1 mm. What is the capacitance per unit length of this cable?

5. In Fig. 25-30, the battery has a potential difference of V = 10.0 V and the five capacitors each have a capacitance of 10.0 µF. What is the charge on (a) capacitor 1 and (b) capacitor 2?
