A charge Q is placed on the plates of a parallel-plate capacitor. The plate spacing is then

Question:

A charge ±Q is placed on the plates of a parallel-plate capacitor. The plate spacing is then increased from L to 2L.

(a) By what factor does the electric potential energy stored in this capacitor change?

(b) Energy must be conserved, so where did this extra energy come from (or go to)?
