If the error in the measurement of the momentum of a particle is (+100%).Then the error in the measurement of kinetic energy is?

Expert Answer
The error in measurement of momentum of the particle (?p) = +100 MeV/c
The relation between KE of a particle and its momentum is given by
Since no information on p, ?m and m is provided it is not possible to evaluate the error in the measurement of KE of the particle.
However if we consider the relativistic kinetic energy of the particle and consider its rest mass mo to be zero (as in case of photons etc)
