Consider two identical dipoles \({D}_{1}\) and \({D}_{2}\) . Charges -q and q of dipole \({D}_{1}\) are located at \((0,0)\) and \(({a}, 0)\) and that of dipole \({D}_{2}\) at ( \(0, {a}\) ) and ( \(0,2 {a}\) ) in \(x\) -y plane, respectively. The net dipole moment of the system is
- \(q a(\hat{i}+\hat{j})\)
- \(-q a(\hat{i}+\hat{j})\)
- \(q a(\hat{i}-\hat{j})\)
- \(-q a(\hat{i}-\hat{j})\)
Answer
(D) -q a( i - j )
