Homework Statement [/b]
A boron nucleus has mass 8.5e-27 kg. If its speed || is 0.961c (that is, ||/c = 0.961), what are the following values?
particle energy = 2.767e-9 J
rest energy = 7.65e-10 J
kinetic energy = 2.002e-9 J
Next an electric force acts on the boron nucleus and does 2.410-9 J of work on the particle. Now what are the following values?
particle energy = ? J
rest energy = 7.65e-10 J
kinetic energy = ? J
