Some spectrometer data for the beta-deay spectrum of 32p is as follows (the elctrons were sent through a magnetic spectrometer, so the value for the product of the magnetic field and path radius are given);

plot in fermi-kurie form (you will have to find the coulomb factor) and find the extrapolated end point energy. compare to a plot with no coulomb fator corretion. what can you conclude from the shape of the first fermi-kurie plot.
