Question

A dipole of dipole moment p is placed in uniform electric field E then torque acting on it is given by (A)  τ = p ⋅ E (B)  τ = p × E (C)  τ = p + E (D)  τ = p - E

Tardigrade Admin · Accepted Answer

When an electric dipole is placed in a uniform electrical field E, the torque on the dipole is given by τ = p × E

Q. A dipole of dipole moment $p$ is placed in uniform electric field $E$ then torque acting on it is given by

$τ = p \cdot E$

$τ = p \times E$

$τ = p + E$

$τ = p - E$

When an electric dipole is placed in a uniform electrical field $E$ , the torque on the dipole is given by $τ = p \times E$

Q. A dipole of dipole moment p​ is placed in uniform electric field E then torque acting on it is given by

τ=p​⋅E

τ=p​×E

τ=p​+E

τ=p​−E
