The Square Plates of a 5000-PF Parallel-Plate Capacitor Measure 50 $0.23 \mathrm {~mm}$

Multiple Choice

The square plates of a 5000-pF parallel-plate capacitor measure 50 mm by 50 mm and are separated by a dielectric that is $0.23 \mathrm {~mm}$ thickand totally fills the region between the plates. The voltage rating (the maximum safe voltage) of the capacitor is $400 \mathrm {~V}$ What is the maximum energy that can be stored in this capacitor without damaging it?

A) 0.40 mJ
B) 0.50 mJ
C) 0.60 mJ
D) 0.70 mJ
E) 0.80 mJ
