Two spherical conductors are separated by a distance much larger than either of their radii. Sphere A has a radius of 46.5 cm and a net charge of -95.5 nC, whereas sphere B, which is initially neutral, has a radius of 94.4 cm. The two spheres are then connected by a thin metal wire. What is the charge on sphere B after equilibrium has been reached? charge on sphere B: -31.52 nc
Two separate parallel long (infinitely long) wires in air and parallel to the ground are separated by a distance D = 1.0m. They are made of conducting material. Each has a radius a 2.0cm, and opposite/equal amounts of charge density (λι = Qit/L and Az = QL). The voltage difference between the wires is ΔΙ. = 440 Vlts. Let's label this pair as pair A (a) What is the potential difference between a pair of long telephone wires (pair B)...
Question 2 1. Two perfectly conducting cylinders ra and rb form an inductor of length d, as shown in the figure below. The total current I flowing on the surface r-α of the inner cylinder is returned through the outer conductor r - b. The medium between the two conductors has magnetic permeability m a) Find the magnetic field intensity H everywhere, disregarding "edge effects" (i.e. assuming that the a, b and hence, it can be considered as infinite) length...
1. There are two straight and parallel wires, separated by a distance D. In the first the current is i, while in the others it is 2i; both in the same sense. At what distance from the first wire will the magnetic field between the wires be zero? 2. A cable that is 5 meters above the ground has a current of 100 A. Determine the magnetic field at ground level. 3. An airplane flies at 200m / s in...
Bob places a neutrally charged conducting ball next to a large, charged plate. The conducting ball is weakly attracted to the plate. What is the net charge on the plate? 1. a) Positive b) Negative c) Neutral (i.e., zero charge) d) Either positive or negative, but it is impossible to tell which A +1 C charge is at the origin, and a second +1 C charge is at position (x,y)-(2 m, 0). How much work is required to move the...
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...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...

6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
