Question

A dipole consisting of two oppositely charged balls connected by a wooden stick is located as shown in the diagram at right. A block of plastic is located nearby, as shown. Locations B, C, and D all lie on a line perpendicular to the axis of the dipole, passing through the midpoint of the dipole. Before selecting answers to the following questions, draw your own diagram of this situation, showing all the fields and charge distributions requested. Answer the following questions by selecting either a direction (a-j) or an orientation of a polarized molecule (1-10) from these diazrams: Part 1 Which of the arrows shown above best indicates the direction of the electric feld at location C, due only to the dipole? Which of the arrows shown above best indicates the direction of the electric field at location D, due only to the dipole? Which of the diagrams shown above best indicates the polarization of a molecule of plastic at location C ? Which of the diagrams shown above best indicates the polarization of a molecule of plastic at location D ? Which of the arrows shown best indicates the direction of the electric field at location B, due only to the dipole? Which of the arrows shown best indicates the direction of the electric field at location B, due only to the plastic block? The magnitude of the electric field at B due to the plastic is less than the magnitude of the electric field at B due to the dipole. Which of the arrows shown best indicates the direction of the net electric field at location B ? Using the diagrammatic conventions discussed in the textbook and in class, a student drew the diagram below to help answer the questions asked above. Which of the following statements about the student's diagram are true? Check all that apply. The diagram is correct; this is just a different way of drawing the polarization. The diagram shows mobile charges; this is wrong because an insulator does not have mobile charged particles. The direction of polarization of the plastic block is wrong.

Answer 1

The direction of the electric field due to the dipole at various locations and the polarization of the plastic block can be identified using the provided diagrams.

Step-by-step explanation:

The direction of the electric field at location C, due only to the dipole, can be identified by the arrow indicated by the letter F. The electric field at location D, due only to the dipole, can be identified by the arrow indicated by the letter E. The polarization of a molecule of plastic at location C can be identified by the diagram indicated by the number 7. The polarization of a molecule of plastic at location D can be identified by the diagram indicated by the number 9. The direction of the electric field at location B, due only to the dipole, can be identified by the arrow indicated by the letter I. The direction of the electric field at location B, due only to the plastic block, can be identified by the arrow indicated by the letter H. The net electric field at location B can be identified by the arrow indicated by the letter J.

The student's diagram is incorrect because it shows mobile charges, which is wrong as an insulator does not have mobile charged particles. The correct statement is that the direction of polarization of the plastic block is wrong.
