A Parallel Plate Capacitor of Capacitance C₀ Has Plates of Area

question 129

Multiple Choice

A parallel plate capacitor of capacitance C₀ has plates of area A with separation d between them.When it is connected to a battery of voltage V₀,it has charge of magnitude Q₀ on its plates.It is then disconnected from the battery and the plates are pulled apart to a separation 2d without discharging them.After the plates are 2d apart,the magnitude of the charge on the plates and the potential difference between them are

• A) \(\frac { 1 } { 2 }\) Q₀, \(\frac { 1 } { 2 }\) V₀
• B)Q₀, \(\frac { 1 } { 2 }\) V₀
• C)Q₀,V₀
• D)Q₀,2V₀
• E)2Q₀,2V₀
