2ai) is just distance/speed
2aii) find to Proper time from relativity equation
2b) Particles will 'see' the distance as shorter so lo is 200 you are trying to find l

Question 3

Post  matthewfrain on Wed May 09, 2012 12:16 am

On question 3... for part a) is this just E=mc^2 rearranged to get the mass? If so what do you use for the Energy of the electron?
Thanks

Finding mass

Post  jmorris on Fri May 11, 2012 6:18 am

You need to find the relativistic mass. The proper mass is 9.11x10-31kg
