Chapter 39: Problem 74
The neutral pion (\(\pi^0\)) is an unstable particle produced in high-energy particle collisions. Its mass is about 264 times that of the electron, and it exists for an average lifetime of 8.4 \(\times\) 10\(^{-17}\) s before decaying into two gamma-ray photons. Using the relationship \(E = mc^2\) between rest mass and energy, find the uncertainty in the mass of the particle and express it as a fraction of the mass.
