Question

Problem 17.44: Torque and force on a dipole. Correct An electric dipole is in a uniform extenal electric field E as shown in the figure (Figure 1) Part C Which of the orientations in Part B is stable? Express your answer in degrees as an integer. View Available Hint(s) ΠνΠ ΑΣφ ? Submit Part D Which of the orientations in Part B is unstable? Express your answer in degrees as an integer. View Available Hint(s) ΠνΠ ΑΣφ ? 0= Submit Part E Show that, for the stable orientation in Part C. the dipole's own electric field opposes the external field for points between the charges. Match the words in the left column to the appropriate blanks in the sentences on the right Reset Help Figure 1 of 1 right The electric field of the dipole is directed from the charge left charge and toward the negative 2. Thus, the electric field of the dipole is to the opposite the positive direction of the external field.

Answer 1

most stable position of a dipole will be when dipole align itself in the direction of electric field ,

opposite of this condition is unstable condition so

PART C

θ = 0 degree

PART D

θ = 180 degree

PART E

directed from positive to negative
