Point charge induced current on a conducting ring

  1. Aug 28, 2014 #1
    I have a conducting copper ring of inner radius a and outer radius b.
    point charges Q pass through the centre of this ring for time dt.
    so I guess I'm suppose to get a step function of induced current or something similar.

    1)what is the equation relating the charge Q to the induced current on the ring?
    2)where should I place the contacts to measure the induced current (inner radius / middle/ outer radius of the ring)?
    3)one of the contacts is placed on the ring and goes to the electro-meter, where does the other contact go to get an electrical circuit? grounded?
    thank you,

    Do you imagine that a current is induced to flow around the ring, or what?
