1. Can I use the surface charge equation:
$$Q = \frac{Vk\epsilon_0A}{d}$$
Where V = Voltage, k = dielectric constant, ϵ0 = permittivity of free space , A = Area of plate and d = distance between plates.
For a conductive plate within an electric field? My thinking is that if the plate is placed within an electric field, then grounded, it essentially becomes the lower potential plate of the electric field generating system. There would no longer be an electric field between the original lower potential plate and the conductive plate placed within the electric field.
2. If this plate is grounded the charge Q will flow to the ground in order to ensure that the plate and ground are at the same potential. If this electric field is constant would there be a continuous flow of charge Q to the ground?
3. If not, how much charge would flow to the ground and is there an equation that relates the size of the plate and the charge that would flow to the ground if it wasn't Q and what effect does the electric field have (i.e does it increase the charge on the surface? or does the need for the potential to be the same as ground negate this effect?)
