defence exam Coast Guard Navik GD (General Duty) 02/2025 Mock Test Series Physics Electric Fields and Gauss' Law A Dipole in an Electric Field
An electric dipole of dipole moment p is placed in a uniform electric field of intensity E. If the initial and the final angular position of the dipole with respect to the electric field is θ1 and θ2 respectively then the amount of work done will be:
1
pE(sinθ1 - sinθ2)
2
pE(cosθ1 - cosθ2)
3
pE.cos(θ2 - θ1)
4
pE.sin(θ2 - θ1)
