A metal plate is connected by a conductor to a ground through a switch. The switch is initially closed. A charge of +Q is brought close to the plate without touching it, and then the switch is opened. After the switch is opened, the charge +Q is removed. What is the charge on the plate then?

Respuesta :

The charge of the plate will be negative

the positive charge will attract electrons from earth to the plate, leaving the switch opened with no return path.

The excess electron then will be trapped on the plate, causing it to be negative with respect to both earth and the charge

hope this helps
