Two parallel plate capacitors with area `A` are connected through a conducting spring of natural length `1` in series as shown. Plates `P` and save fixed positions at separation `d`. Now the plates are connected by a battery of `emf xi` as shown. If the extension in the spring in equilibrium is equal to the separation between the plates, find the spring constant `k`.
