Question

why brass increase the electrostatic force of attraction​

Answer 1

Answer:

heya mate ☺

The brass plate is a conductor, so the potential will be the same on both sides. The thickness of the brass plate therefore subtracts from the effective distance between the two charges, making the electric field strength higher in the remaining open space between the charges

Answer 2

That is because the brass plate is a conductor, so the potential will be the same on both sides. The thickness of the brass plate therefore subtracts from the effective distance between the two charges, making the electric field strength higher in the remaining open space between the charges. Therefore, brass increases the electrostatic force of attraction.
