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.While it is connected to the battery the space between the plates is filled with a material of dielectric constant 3.After the dielectric is added,the magnitude of the charge on the plates and the potential difference between them are

A) $\frac { 1 } { 3 }$ Q₀, $\frac { 1 } { 3 }$ V₀
B) Q₀, $\frac { 1 } { 3 }$ V₀
C) Q₀,V₀
D) 3Q₀,V₀
E) 3Q₀,3V₀
