1) A negatively charged Teflon (plastic) rod is held near two initially neutral aluminum pie plates that are touching as shown at right. The plates are held using insulating cups. The Teflon rod never touched the pie plates, and no sparks have jumped. Negatively charged Teflon rod a. Is the magnitude of the net charge of the small pie plate greater than, less than, or equal to the magnitude of the net charge of the large pie plate? If the...

4. A negatively charged rod is brought near a metal sphere supported by an insulating stand point) without touching it. What happens to the free electrons in the sphere? OThey pass from the sphere into the stand. OThey are pushed out of the sphere and into the air OThey are pulled out of the sphere and into the rod. OThey shift away from the rod on the sphere.

A negatively charged rod is brought near an
electroscope without touching it. The leaves are initially
separated, and as the rod is brought closer, the leaves move
further apart. What is the charge on the electroscope?

suppose you negatively charge a teflon rod by rubbing it with rabbit fur. which statement in the list is false? and why? a) The rod can attract small bits of paper, due to microscopic polarization of the paper by the electric field generated by the rod. b) The rabbit's fur will become positively charged. c) If the rod is brought near a metal object, the object will become macroscopically polarized, with its free electrons pulling toward the rod leaving a...

Problem 4 Select the answer which corresponds to the statements below. A negatively charged glass rod repels an object suspended by a non-conducting thread. The charge on the object is Two neutral metal spheres, #1 and #2, are mounted on insulating supports. They are connected by a wire. A positively charged glass rod is brought near sphere #1 . The wire connecting the spheres is removed and the charged rod is then taken away. Now the charge on...

a) You're holding a small metal ball suspended on a piece of insulating string from the ceiling. You and the ball are both initially electrically neutral. A positively charged rod is brought near to the metal ball; you then let go of the metal ball. You now have a positive electric charge. This process is called charging by 1.) Electroscope. 2.) Insulation. 3.) Conduction. 4.) Induction. b) Charged glass and plastic rods hang by threads. An object attracts the glass...

Problem 4 Select the answer which corresponds to the statements below cemat ten A negatively charged glass rod atracts an object suspended by a non-conducting thread. The charge on the object is A positive point charge is brought near the outside surface of a neutral conducting sphere and released. The initial position of the point charge is on the on the positive x axis and the sphere is centered A positively charged ball is brought close to a neutral isolated...

A long insulating rod suspended by insulating wires.Assume that the rod is initially electrically neutral. Forconvenience, we will refer to the left end of the rod as end A, andthe right end of the rod as end B . In the answer options for thisproblem, "weakly attracted/repelled" means "attracted/repelled witha force of magnitude similar to that which would exist between twoballs, one of which is charged, and the other acquires a smallinduced charge". An attractive/repulsive force greater than thisshould be...

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...
