Question: A thin wire ring of radius a carrying a charge q approaches the observation point P so that its centre moves rectilinearly with a constant

A thin wire ring of radius a carrying a charge q approaches the observation point P so that its centre moves rectilinearly with a constant velocity v. The plane of the ring remains perpendicular to the motion direction. At what distance inform the point P will the ring be located at the moment when the displacement current density at the point P becomes maximum? What is the magnitude of this maximum density?
