Moving Plates of Capacitor Closer

SATPHY-7DYJGC

A capacitor is charged by a battery. While still connected to the battery, the plates of the capacitor are moved closer together.

What happens to the charge on the plates, the voltage across the plates, and the capacitance of the capacitor as a result of moving the plates closer together?

A
Capacitor Values after Plates are Moved Closer Together
Charges on Plates same
Voltage Across Plates larger
Capacitance larger
B
Capacitor Values after Plates are Moved Closer Together
Charges on Plates same
Voltage Across Plates smaller
Capacitance larger
C
Capacitor Values after Plates are Moved Closer Together
Charges on Plates larger
Voltage Across Plates same
Capacitance same
D
Capacitor Values after Plates are Moved Closer Together
Charges on Plates larger
Voltage Across Plates same
Capacitance larger
E
Capacitor Values after Plates are Moved Closer Together
Charges on Plates larger
Voltage Across Plates larger
Capacitance larger
