A Parallel Plate Capacitor of Capacitance C₀ Has Plates of Area

question 121

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 new capacitance and the potential difference between the plates are

• A) \(\frac { 1 } { 2 }\) C₀, \(\frac { 1 } { 2 }\) V₀
• B) \(\frac { 1 } { 2 }\) C₀,V₀
• C) \(\frac { 1 } { 2 }\) C₀,2V₀
• D)C₀,2V₀
• E)2C₀,2V₀
