Question
An air filled parallel-plate capacitor is connected to a 12 Volts battery, the
battery is disconnected when it is fully charged to 7.3 nC. The separation
distance between the plates is d1= 8 cm. Now, If the plates are moved to a
new distance d233 cm. the new energy stored in the capacitor is
O a. 13.14 nJ
O b. 8.21 nJ
O c. 1.64 nJ
O d. 10.96 nJ
O e. 5.47 nJ
O f. 16.42 nJ
