CBSE Class 12-science Answered
A electric dipole consisting of an electron and proton seprated by a distance of 4m is placed in a uniform electric field intensity 3N/C at an angle 30 with the field. Calculate the dipole moment and torque acting on the dipole.

Expert Answer
dipole moment p = q×l = 1.6×10-19×4 = 6.4×10-19 C-m
Torque = p×E = p×E×sinθ = 6.4×10-19×3×(1/2) = 9.6×10-19 Nm
E is electric field intensity and θ is angle between dipole and electric field
