Homework Statement
Electron e, mass m, moves in constant homogeneous magnetic field H. Find time interval for electron's energy to decrease 10 times due to emission.
Homework Equations
I know for sure from the class that m*a=(e/c)*(v⊥)*H (Lorentz force); intensity -I=dE/dt=-2e4v⊥2H2/(3m2c5)
dE/dt=(m/2)*d(v⊥2)/dt;
here we have d(v⊥2)/dt=-4e4v⊥2H2/(3m3c5)
The Attempt at a Solution
The problem is in the next step. What should I do further? I have a differential equation. May I take an integral over d(v⊥2) from v2 to v2/10 and on the other side of equation take an integral over dt from 0 to t?[/sup]
