A Parallel Plate Capacitor of Capacitance C₀ Has Plates of Area

question 8

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 space between the plates is filled with a material of dielectric constant 3.After the dielectric is added,the magnitudes of the capacitance and the potential difference between the plates are

• A) \[\frac { 1 } { 3 }\] C₀, \[\frac { 1 } { 3 }\] V₀.
• B)C₀, \(\frac { 1 } { 3 }\) V₀.
• C)C₀,V₀.
• D)3C₀, \(\frac { 1 } { 3 }\) V₀.
• E)3C₀,3V₀.
