An Air-Filled Parallel Plate Capacitor Is Connected to a Battery

question 67

Multiple Choice

An air-filled parallel plate capacitor is connected to a battery of voltage V_o.There is charge Q_o on each plate,energy U_o stored between the plates and an electric field of E_o between the plates.The capacitor is then removed from the battery and then a dielectric material with a dielectric constant of K is then placed between the plates of the capacitor.What are the new values of V,Q,U,and E?

• A)V_o/K,KQ_o,U_o,E_o/K
• B)KV_o,Q_o,K²U_o,E_o/K
• C)V_o/K,Q_o,U_o/K,E_o/K
• D)V_o,Q_o/K,U_o/K,E_o
• E)V_o,KQ_o,KU_o,E_o
