150 pJ of energy is stored in a 1.0 cm times 1.0 cm times 1.0 cm region of uniform electric field. What is the electric field strength?

Two 2.4 cm diameter disks spaced 1.5 mm apart form a parallel-plate capacitor. The electric field between the disks is 4.3×10^5 V/m. What is the voltage across the capacitor? How much charge is on each disk? An electron is launched from the negative plate...
