A ring of diameter d is rotated in a uniform electric field until the position of maximum electric flux is found. The flux is found to be `phi`. What is the electric field strength?

A circular loop of diameter d is rotated in a uniform electric field until the position of maximum electric flux is found. The flux in this position is measured to be phi .What is the electric field strength?
