Point charge induced current on a conducting ring

[Caltechian]

Hello,
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,

I'm sorry you are not finding help at the moment. Is there any additional information you can share with us?

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