JEE Main Physics question

If an electric dipole is situated in a non-uniform electric field, then

(A)ΣF = 0, Στ = 0
(B)ΣF ≠ 0, but Στ = 0Correct
(C)ΣF = 0, but Στ ≠ 0
(D)ΣF ≠ 0, Στ ≠ 0Correct

Answer: (B),(D)

Solution

In a non-uniform field, the net force on a dipole is generally non-zero (ΣF ≠ 0) since the field strength differs at the two charges. The net torque can be
