Answer 1

An electric dipole has a fixed dipole moment p → , which makes angle θ with respect to x-axis. When subjected to an electric field → ∧ E E 1= i , it experiences a torque → ∧ T1= τ k . When subjected to another electric field → ∧ E 3 E 2 1 = j it experiences a torque → → T T 2 1 =− . The angle θ is : (1) 308 (2) 458 (3) 608 (4) 908
