Explain in detail, including diagrams, what happens when a negatively charged tape is brought near your finger.

Short Answer

Expert verified

The negatively charged tape gets attracted to the finger.

Step by step solution

01

Significance of the law of attraction

The law of attraction states that like charges repel and unlike charges attract each other. Moreover, a charged particle also attracts a neutral object.

02

Explanation of the given statement

The diagram has been drawn below-

The finger has dipoles, so when the negatively charged tape is brought near to the finger, then the electric field of the finger goes to the tape and the electric field of the tape goes to the finger which creates the attraction.

Thus, the negatively charged tape gets attracted to the finger.

A positive charge is located between a neutral block of plastic and a neutral block of copper (Figure 14.68). Draw the approximate charge distribution for this situation.

8 (a) An object can be both charged and polarized. On a negatively charged metal ball, the charge is spread uniformly all over the surface (Figure 14.42). If a positive charge is brought near, the charged ball will polarize. If any of the following quantities is zero, state this explicitly. (1) Draw the approximate final charge distribution on the ball. (2) At the center, draw the electric field due to the external positive charge. (3) At the center, draw the electric field due to the charge on the surface of the ball. (4) At the center, draw the net electric field.

(b) Next, consider a negatively charged plastic pen that is brought near a neutral solid metal cylinder (Figure 14.43). If any of the following quantities is zero, state this explicitly. (1) Show the approximate charge distribution for the metal cylinder. (2) Draw a vector representing the net force exerted by the pen on the metal cylinder, and explain your force vector briefly but completely, including all relevant interactions. (3) At the center, draw the electric field due to the external negative charge. (4) At the center, draw the electric field due to the charge on the surface of the ball. (5) At the center, draw the net electric field.

(c) Replace the solid metal cylinder with a solid plastic cylinder. (1) Show the approximate charge distribution for the plastic cylinder. (2) Draw a vector representing the net force exerted by the pen on the plastic cylinder. (3) Explain your force vector briefly but completely, including all relevant interactions.

A metal ball with diameter of a half a centimeter and hanging from an insulating thread is charged up with 1脳1010excess electrons. An initially uncharged identical metal ball hanging from an insulating thread is brought in contact with the first ball, then moved away, and they hang so that the distance between their centers is 20cm.

(a) Calculate the electric force one ball exerts on the other, and state whether it is attractive or repulsive. If you have to make any simplifying assumptions, state them explicitly and justify them.

(b) Now the balls are moved so that as they hang, the distance between their centers is only 5cm. Naively one would expect the force that one ball exerts on the other to increase by a factor of 42=16, but in real life the increase is a bit less than a factor of role="math" localid="1661330186132" 16. Explain why, including a diagram. (Nothing but the distance between centers is changed鈥攖he charge on each ball is unchanged, and no other objects are around.)

(a) Which of the diagrams () in Figure correctly displays the polarization of a metal sphere by an electric field that points to the left, using the conventions discussed in this chapter? (b) Which of the diagrams () in Figurecorrectly displays the polarization of a plastic sphere by an electric field that points to the left, using the conventions discussed in this chapter?

This question focuses on reasoning about equilibrium inside the nickel block shown in Figure 14.92. Start with these premises:

  • The definition of equilibrium inside a conductor and
  • The relationship between average drift speed and electric field

in a conductor to reason about which situations are possibleinside the nickel block at equilibrium. Some of the situations listed below are possible, some are ruled out by one premise, and some are ruled out by two premises. If a situation is ruled out by two premises, choose both.

Case 1:\({\bf{\bar v = 0}}\)and \({{\bf{E}}_{{\bf{net}}}}{\bf{ = 0}}\) (1) Possible, (2) Not possible by definition of equilibrium, (3) Not possible because \({\bf{\bar v = u}}{{\bf{E}}_{{\bf{net}}}}\)

Case 2:\({\bf{\bar v = 0}}\)and \({{\bf{E}}_{{\bf{net}}}}{\bf{ > 0}}\) (1) Possible, (2) Not possible by definition of equilibrium, (3) Not possible because \({\bf{\bar v = u}}{{\bf{E}}_{{\bf{net}}}}\)

Case 3:\({\bf{\bar v > 0}}\)and \({{\bf{E}}_{{\bf{net}}}}{\bf{ = 0}}\) (1) Possible, (2) Not possible by definition of equilibrium, (3) Not possible because \({\bf{\bar v = u}}{{\bf{E}}_{{\bf{net}}}}\)

Case 4:\({\bf{\bar v > 0}}\)and \({{\bf{E}}_{{\bf{net}}}}{\bf{ > 0}}\) (1) Possible, (2) Not possible by definition of equilibrium, (3) Not possible because \({\bf{\bar v = u}}{{\bf{E}}_{{\bf{net}}}}\)

Now that you have considered each case, in equilibrium, which one is the only situation that is physically possible? (1) Case 1, (2) Case 2, (3) Case 3, (4) Case 4
