Electric Charges and Fields · Electric dipole

Three charges +2q+2q, +3q+3q and −4q-4q are situated at (0,−3a)(0, -3a), (2a,0)(2a, 0) and (−2a,0)(-2a, 0) respectively in the xyxy plane. The resultant dipole moment about origin is
  1. (1)2qa(3j^−i^)2qa\left(3\hat j - \hat i\right)
  2. (2)2qa(3i^−7j^)2qa\left(3\hat i - 7\hat j\right)
  3. (3)2qa(7i^−3j^)2qa\left(7\hat i - 3\hat j\right)
  4. (4)2qa(3j^−7i^)2qa\left(3\hat j - 7\hat i\right)
We corrected a printing error in the original paper

Source printed “+2q+2q. +3q+3q” (full stop for the comma).
