## Torque on a dipole in a uniform electric field A dipole is kept in a uniform electric field making an angle θ with the field. +9qe → E -9qe → **Net force** - Force on +qe is Fie = +qe - F-q = -qe - Net force = 0 **No linear force** **Torque** Couple of force and opposite force acting at two different points Create a torque - τ = F x r = qE x 2l sin θ = **qE 2l sin θ**
