Question

Define dipole moment. Calculate the amount of work done in rotating

Answer 1

hi mate, I have a great answer of your question ,

For an electric dipole p in a uniform field E we write the work done by an external agent in rotating dipole as dW=pEsinθdθ.

I'm having trouble understanding where this equation comes from and why W=∫

θf

θi

pEsinθdθ is true, as the only definition of work I know is W=Fs.

maybe it's help you
