When the capacitor is connected to dc source, it gets charged. The battery is then disconnected, so no more charge can flow in. On removing dielectric, capacitance decreases.
Energy stored (u= 2Cq2) will increase
Potential (V= Cq) will also increase
Electric field (E= DV) will increase
Two capacitor of a capacitance 4uf and 6uf are connected in series to a 100volt DC
