does an electric dipole always experience a torque when placed in a uniform electric field?
ritika677:
ok
thnxx
see for a electric dipole , the torque naturally depends on the angle of inclination of the dipole to the external constant field applied
when they are in the same direction , the torque is zero
oh
ohhh thnx
thank u soo much
✔✔
the expression goes as Tau ( T) = - p e sin ⊙ , where p is the dipole moment and E = electric field
okay

Answer...
Torque,
τ = pE sinθ
if θ = 0° or 180° , then
τ = 0
so , it's not necessary that the dipole will always experience torque.

As torque = p× E
= pE sin( a)
If dipole moment and electric field making an angle 0 or 180 that is it is in stable or unstable equilibrium,it experiences no torque
as sin0 = 0 and sin180= 0
So torque = 0
