MCQ
An electric dipole has a fixed dipole moment `vec "p"`, which makes angle `theta` with respect to x-axis. When subjected to an electric field `vec"E"_1 = "E"hat"i"`, it experiences a torque `vec "T"_1 = tau hat"k"`. When subjected to another electric field `vec "E"_2 = sqrt3 "E"_1 hat "j"` it experiences torque `vec "T"_2 = ~ vec "T"_1` The angle `theta` is ____________.
  • A
    30°
  • B
    90°
  • ✓
    60°
  • D
    45°
✓
