08.42: A parallel-plate capacito/rhrz7,( k v-ddj3rqmyv7j 6tr is connected *t6vd ,;g,md7njfldcv p l+d7 to a battery. Without disconnecting the capacitor, a student pulls the capacitor’s plates *7dj+6vdntfml ,d; lv d,c7 gpapart so that the plate separation doubles. As a result of this action, what happens to the voltage across the capacitor and the energy stored by the capacitor?
A. the voltage doubles; the energy stays the same
B. the voltage halves; the energy doubles
C. the voltage doubles; the energy halves
D. the voltage stays the same; the energy halves
E. the voltage stays the same; the energy doubles
