Question

In a cyclotron, this force points in the opposite direction of the velocity of the particle, for 10 points each:
[10h] Identify this recoil force on an accelerating charged particle that is the result of the emission of radiation. This force is proportional to the charge squared times jerk.
ANSWER: Abraham-Lorentz force [or Lorentz-Abraham force; or Abraham-Lorentz-Dirac force; accept radiation reaction force; accept radiation damping force; accept self-force]
[10m] The total power radiated by an accelerating particle moving nonrelativistically can be calculated by this formula, the derivative of the Abraham-Lorentz formula. It states that the time-averaged power is proportional to acceleration squared.
ANSWER: Larmor formula
[10e] The relativistic generalization of the Larmor formula is given by a “retarded” one of these functions, named for Liénard and Wiechert. Ohm’s law states that this quantity is equal to current times resistance.
ANSWER: voltage [or electric potential; prompt on retarded potential; reject “potential energy”]
