A glass rod is given positive charge by rubbing it against silk. The glass rod is then rubbed against a metal slab (on an insulating stand), transferring the positive charge on the rod to the slab. Which of the following statements is true concerning the electric field at a point just outside the upper surface of the slab? It is zero because the electric field is always zero for isolated conductors. It is parallel to the surface. It is perpendicular to the surface. It can have nonzero components perpendicular to and parallel to the surface of the conductor. None of these

Three identical conducting spheres are fixed along a single line. The middle sphere is equidistant from the other two so that the center-to-center distance between the middle sphere and either of the other two is 0.125 m. Initially, only the middle sphere is charged, with qmiddle = +35.6 nC. The middle sphere is later connected by a conducting wire to the sphere on the left. The wire is removed and then used to connect the middle sphere to the sphere on the right. The wire is again removed. a. C What is the charge on each sphere? b.

An infinite line of positive charge lies along the y axis, with charge density = 2.00 C/m. A dipole is placed with its center along the x axis at x = 25.0 cm. The dipole consists of two charges 10.0 C separated by 2.00 cm. The axis of the dipole makes an angle of 35.0 with the x axis, and the positive charge is farther from the line of charge than the negative charge. Find the net force exerted on the dipole.
