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?

  • College physics -

    Energy stored in E-field =
    (1/2)*(epsilono)*E^2*(Volume)

    Make sure the volume is in m^3.

    You have been given the energy, so solve for E
