Slow-light enhancement of radiation pressure in an omnidirectional-reflector waveguide
... where F is the force due to area A, and Ufield is equal to the integral of the electromagnetic energy density over A and z. The value of Fd / Ufield is always positive: The effect of the light in the guided mode is to push the two films apart. For each value of a / d, the force increases with decrea ...

CHAPTER 16: Electric Charge and Electric Field Answers to Questions
... 11. The electric force is conservative. You can “store” energy in it, and get the energy back. For example, moving a positive charge close to another stationary positive charge takes work (similar to lifting an object in the Earth’s gravitational field), but if the positive charge is then released, ...
