Each of the protons in a particle beam has a kinetic energy of 3.05 10-15 J. What are the magnitude and direction of the electric field that will stop these protons in a distance of 1.15 m?

  • Physics -

    Voltage * charge = energy

    So you know what voltage you need.

    E * distance = Voltage

    so you know distance = 1.15 so solve for E
