Conducting Spheres Problem 4. Identical isolated conducting spheres1 and 2 have equal charges and are seperated by a distance that is large compared with their diameters (a). The electrostatic force acting on sphere 2 due to sphere 1 is F. Suppose now that a third identical sphere 3, having an insulated handle and initially neutral, is touched first to sphere 1 and then to sphere 2 and finally removed. The electrostaticforce that now acts on 2 is f. What is the ratio f/F See attached file for full problem description.

Electrostatic Charges & Fields

Problem 13 :- In figure 21-26 in attached file 3 particle 1 of charge +1.0 uC and particle 2 of charge -3.0 uC are held at separation L = 10.0cm on an x axis. If particle 3 of unknown charge (q3) is to be located such that the net electrostatic force on it from particles1 and 2 is zero. What must be the (a)x axis and (b) y axis co-ordinates of particle3?? Problem 8. In figure 22-30 in attached file 4 particle 1 of charge q1= -5.00q and particle 2 of charge +2.00q are fixed to an x axis. (a) As a multiple of distance L, at what coordinate on the axis is the net electric field of the particles zero? (b) Sketch the electric field lines. Problem 26.

Electric Field Charge

Please see attached file 4. for the following problems: 6. At each point on the surface of the cube shown in Figure 23-27, the electric field is parallel to z-axis. The length of each edge of the cube is 3.0 m. On the top face of the cube, E = -34k N/C, and at the bottom face E = +20k N/C. Determine the net charge contained within the cube. 29. A long, straight wire has fixed negative charge with a linear charge density of magnitude of 3.6 nC/m. The wire is to be enclosed by a coaxial, thin walled nonconducting cylindrical shell of radius 1.5 cm. The shell is to have positive charge on its outside surface with a surface charge density sigma that makes the net external electric field ze... click for more
