Question: We have an electron moving at a velocity v0. The electron is now decelerated at a rate ?a? (constant) to velocity 0. Let v0<< c. The fraction of kinetic energy lost as radiation is:
f = μ0qxa/yΠmv0c
In above problem, if the initial velocity is 105m/s. Electron travels at 30 angstrom, the radiation loss from conductor is z × 10-11.The value of x + y + z is?
