Question

Derive an expression for the torque experienced by the an electric dipole when placed in a uniform electric field​

Answer 1

Answer:

here is the answer

Explanation:

we have to draw a uniform electric field and kept a dipole in it , the direction of dipole moment (P) along E so , the distance b/w two as 2l

since, the force become zero s it can't have linear motion .

by applying formula of torque we can calculate it .
