Hi!
I am trying to find the time for an electron to accelerate in a uniform electric field from u1 to u2.
In the textbook, I found that time is found by integrating d(u/(1-u^2/c^2)^(1/2))=(qE/m_0)⋅dt
and they get u/(1-u^2/c^2)^(1/2) = qEt/m_0 by integrating from t=0 and u=0 to t=t and u=u
I don't quite get the left hand side of the equation, what is it integrating with respect to? what if the particle starts at t=0 and u=u1 and end at t=t1 and u=u2?
Thanks a lot
