Which of the following statements is correct for an electric dipole placed along the direction of a non-uniform electric field?
- A \( F_{net} = 0; \tau_{net} = 0 \)
- B \( F_{net} \neq 0; \tau_{net} = 0 \)
- C \( F_{net} \neq 0; \tau_{net} \neq 0 \)
- D \( F_{net} = 0; \tau_{net} \neq 0 \)
Answer & Solution
Correct Answer
(B) \( F_{net} \neq 0; \tau_{net} = 0 \)
Step-by-step Solution
Detailed explanation
In a non-uniform field, the forces on the two charges of the dipole don't cancel out, resulting in a nonzero net force \(\left(F_{\text {net }} \neq 0\right)\). However, because the dipole is placed along the direction of the field (parallel or anti-parallel), the lines of force…
