A Parallel Plate Capacitor of Capacitance C₀ Has Plates of Area

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.The plates are pulled apart to a separation 2d while the capacitor remains connected to the battery.After the plates are 2d apart,the capacitance of the capacitor and the magnitude of the charge on the plates are

A) $\frac { 1 } { 2 }$ C₀, $\frac { 1 } { 2 }$ Q₀
B) $\frac { 1 } { 2 }$ C₀,Q₀
C) C₀,Q₀
D) 2C₀,Q₀
E) 2C₀,2Q₀
