A charge q is placed at (1, 2, 1) and other charge –q is placed at (0, 1, 0) such that they form an electric dipole. There exist a uniform electric field \(\vec{E}=2 \hat{i}+3 \hat{j}\). What is torque experienced by the dipole.
- \(q(3 \hat{i}+2 \hat{j}+\hat{k})\)N.m
- \(q(-3 \hat{i}+2 \hat{j}+\hat{k}) N \cdot m\)
- \(q(-3 \hat{i}+2 \hat{j}-\hat{k}) N . m\)
- \(q(\hat{i}-2 \hat{j}+\hat{k}) N \cdot m\)
Answer
(B) q(-3 i +2 j + k ) N m
