Two parallel circular metal plates X and Y, each of diameter 18 cm, have a separation of 9.0 cm. A potential difference of 9.0 V is applied between them. [diagram: plate X, plate Y, 18 cm, 9.0 cm, 6.0 cm, 3.0 cm, P, 9.0 V, +, –] Point P is 6.0 cm from the surface of plate X and 3.0 cm from the surface of plate Y. What is the electric field strength at P?
