When a charged balloon sticks to a wall, the downward
gravitational force is balanced by an upward static friction force.
The normal force is provided by the electrical attraction between
the charged balloon and the equal but oppositely charged
polarization induced in the wall's molecules.
If the mass of a balloon is 2.1 g, its coefficient of static
friction with the wall is 0.70, and the average distance between
the opposite charges is 0.80 mm, what minimum amount of charge...

1) Two identical small charged spheres are a certain distance apart, and each one initially experiences an electrostatic force of magnitude F due to the other. With time, charge gradually diminishes on both spheres by leaking off. When each of the spheres has lost half its initial charge, what will be the magnitude of the electrostatic force on each one? A) 1/16 F B) 1/8 F Coulomos coulombs Law C) 1/4 F D) 1/2 F E) 1/2 F 2) Two...

Problem 4: Read Appendix 2 below (Sec. 1.4.1 of Kasap) and then solve. A metallic back contact is applied to the CdTe solar cell of Problem 1 using a set up similar to that described in Figure 1.74 (b) on the next page. To form the metallic back contact, two evaporation sources are used, Cu and Au. An initial 3 nm layer of Cu is deposited first and then 30 nm of Au is deposited. After these depositions, the sample...

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...
