13) Bombardment with ultraviolet light removes electrons from a copper sphere (radius 1.2cm, surface area 18cm², volume 7.2cm) via the photoelectric effect. This results in a charge density of +24 nC per appropriate quantity (cm, cm? or cm”). What is the total charge?
15) A stack of five uncharged identical copper spheres (radius 1.2cm, surface area 18cm², volume 7.2cm) has a total end-to-end resistance of 1.3u82. What is the resistance of one sphere?

8) A Gaussian spherical surface of radius 0.20 m completely surrounds a collection of charges. A uniform electric field emerging from the charges has a value of.51 NC. a) Find the electric flux through the surface if the collection consists of a single charge. Use the Gauss Law to determine the magnitude of this charge inside the sphere. b)
Consider a sphere of radius a with a uniform charge distribution over its volume, and a total charge of q_o. Use Gauss's Law to calculate the electric field outside the sphere, and then inside the sphere. Solve the general problem in r, recognizing that problem spherical symmetry. Draw a graph of the electric field the has the surface of the strength as a function of noting where if the surface of the sphere is (a). Some hints: the surface area...
#8 Gauss's Law and The Shell Theorem Consider a hollow sphere with charge uni- formly distributed on its surface. Suppose the total charge is Q, where Q may be positive or negative Recall that Gauss's law as we have seen it is: Qenclosed ΣΕ A = EO where A = 47tr2 is the total area of the Gaussian surface Suppose the sphere radius is Ro and r > Ro. In terms of Gauss's Law, the reason why the electric field...
Question 1 (compulsory): The following set of charges is given in free space Charge σ,--40 nC/m Number and type of charge #1 , charged spherical shell of radius Ri-10 cm carrying uniform surface charge density σ #2, charged spherical shell of radius R2-5 cm carrying uniform surface charge density Ơ Location (0, 0, 0) m (position of the centre of the sphere) (0, 0, 0) m (position of the centre of the sphere σ,-160 nC/m2 The positions of the spheres'...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
