試題詳解

23. The electric dipole moment p=pk of a molecular is formed by two equal charges of opposite sign +q and -q, separated by a distance d = 2.4 x (m) and given q=2.0× (Coul). The electric dipole is placed in a uniform electric field E=3.5×10⁵i+4.2×10⁵k (N/Coul) as shown in Figure 8. Find the magnitudes of the electric dipole moment of this molecular and the torque |т| exerted on the electric dipole. 

(A) (Coulm), and (N.m)

(B) (Coul·m), and (N.m)

(C) (Coul·m), and (N.m) 

(D) (Coul-m), and (N.m)
