A dipole is placed in an electric field E⃗ in the direction shown in figure. In which direction will it move? [Diagram: Image]

G1 Physics · Accepted Answer

Step 1: In a non-uniform electric field, a dipole may experience net force toward stronger field if aligned or toward weaker field if anti-aligned. Step 2: For the orientation in source figure, shifting left changes dipole energy according to U = −p⃗·E⃗. Step 3: Refer to direction and potential trend in original diagram; printed answer option (C).
