Question

A parallel plate capacitor is charged to a potential difference V by a dc source. The capacitor is then disconnected from the source. If the distance between the plates is doubled, state with reason how the following change:1) electric field between the plates 2) capacitance, and 3) energy stored in the capacitor

Answer 1

electric field is also doubled
capacitance becomes half

pls tell if answer is right or not I m not confident about the answer
