Question

An electric dipole of dipole moment p is placed in a uniform electric field. Write
the expression for the torque experienced by the dipole. Identify two pairs of
perpendicular vectors in the expression. Show diagrammatically the orientation
of the dipole in the field for which the torque is
(i) Maximum
(ii) Half the maximum value
(iii) Zero.

Answer 1

Answer:

Explanation:

τ⃗ = p⃗ × E⃗ Pairs of perpendicular vector (a) (τ⃗, p⃗) (b) (τ⃗, E⃗) (i) Magnitude of torque τ = pEsintheta For maximum torque (sintheta)max ...

Identify the two pAirs of perpendicular vectors in expresssion . Show diagrammatically the orientation of the dipole in the field for which torque is maximum , half the maximum value, zero. ... An elrctric dipole of dipole moment p is placed in a uniform electric field E . Write the expression for torque experienced by dipole .
