an electric dipole of length 4 cm,when placed with its axis making an angle of 60 degree with a uniform electric field experiences a torque of 4Nm.calculate the magnitude of the electric field and the potential energyof the dipole ,if the dipole has charges of 8nC
τ = P X E = PE sinθ = charge X length of dipole X electric field X sinθ
θ is the angle between dipole moment P and electric field E
Potential energy = PE(1 - cosθ)
rest is calculation
