a. Strength of electric field inside the capacitor remains unchanged, if battery is disconnected before pulling the plates.
b. During the process, work is done by external force applied to pull the plates irrespective of whether the battery is disconnected or not.
c.Strain energy in the capacitor decreases if the battery remains connected
