(a) Find the electric dipole moment of the object.
-1E-11 C-mi+[
x
Your response differs from the correct answer by more than 10%. Double check your calculations. C. mj
(b) The object is placed in an electric field E=(7.80 x 10³ 1-4.90 x 103 ) N/C.Find the torque acting on the object.
X
Your response differs from the correct answer by more than 10%. Double check your calculations. N mk
(c) Find the potential energy of the object-field system when the object is in this orientation.
x
Your response is within 10% of the correct value. This may be due to roundoff errot, or you could have a mistake in your
calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. J
(d) Assuming the orientation of the object can change, find the difference between the maximum and the minimum potential
energies of the system.
