The electric potential energy in a capacitor will be 5 × 10 ⁻⁹ J.
A capacitor is a device that can store electrical energy. It is a two-conductor configuration separated by an insulating medium that carries charges of equal size and opposite sign.
An electric insulator or vacuum, such as glass, paper, air, or a semiconductor termed a dielectric, can be used as the non-conductive zone.
The electric potential energy in a capacitor is found as;
[tex]\rm E = \frac{1}{2} QV[/tex]
[tex]\rm E = \frac{1}{2}\times 1.0 \times 10^{-10} \ C \times 100 \ V \\\\ E= 5 \times 10^{-9} \ J[/tex]
Hence the electric potential energy in a capacitor will be 5 × 10 ⁻⁹ J.
