An electric dipole of dipole moment \(\overrightarrow{\mathrm{p}}\) is placed in uniform electric field \(\overrightarrow{\mathrm{E}}\), with \(\overrightarrow{\mathrm{p}}\) parallel to \(\overrightarrow{\mathrm{E}}\). It is then rotated by an angle of θ. The work done is
- pE sin θ
- pE cos θ
- pE (1 – cos θ)
- pE (1 – sinθ)
Answer
(C) pE (1 – cos θ )
