A water molecule is built as an isosceles triangle; the two hydrogen atoms are separated by 1.5x10-10m, and the oxygen is a distance 1x10-10m from either of the hydrogens. Treating the hydrogens as point charges, each of +e, and the oxygen as a point charge of -2e, estimate the total electric potential energy stored in this molecule.

An air capacitor is made up of two parallel plates, each with an area of 10.7 cm^2 separated at a distance of 2.5 mm. A potential difference of 44 volts is applied to these plates. Calculate the surface charge density. answer nC/m^2 and two decimal places
