Consider two oppositely charged, isolated parallel plates separated by distance D, with capacitance C, charge Q, and stored energy U. For each statement below, select "True" or "False".

1.Increasing D, increases the E field.
2.Because of charge conservation, inserting a dielectric leaves C unchanged.
3. Because of energy conservation, inserting a dielectric leaves U unchanged.
4. When D is halved, Q stays the same.
5. Inserting a dielectric increases Q.
6. When D is doubled, C is halved.
7. When D is doubled, U is unchanged.
