electron is deflected in a circular path
electron speed = 2.7 x 10^8 m/s
diameter = 3cm
magnetic field = 0.24T
1. work out charge to mass ratio - 7.5 x 10^10
2. the textbook value is 1.76 x 10^11 - comment on this value
The answer is given as electron traveling close to speed of light so relativistic effects increases mass.
But increasing the mass will decrease the charge to mass ratio, rather than increase it. Which is what is given by the textbook value...
