However, I attempted to do the full integral, expecting the other two directions to cancel out, but my integrals don't seem to work out to the correct values. The electric field vector points in only one direction, so there is really only one integral to do. Electric charges attract and repel by exerting forces on each other. By symmetry, the electric field must point radially. Also called the permittivity of free space, it is an ideal physical constant that represents the absolute dielectric permittivity of a vacuum. The curl of any gradient is zero so that the requirement Equation ( 7.2.5) can be satisfied by putting. Easily polarized materials have larger dielectric constants The Epsilon Naught value is constant at any part of the universe. When I shut down my Bloomberg and exited the Mayfair office of my hedge fund for the final time a few years ago, one of the last prices I saw flickering on my screen was the bond price of a Chinese real estate developer called Evergrande.
