The Attempt at a Solution


Please, please, please could someone tell me where the mass m0 term comes from? I'm at the end of a 7 hour revision session and need help.

The ##m_0## inside the parentheses has been put in for convenience. It is accounted for in the number ##4.9 \times 10^{15}## which includes a factor of ##m_0^{3/2}##.

Thanks very much for that, it had me very confused.
 
It appears to me that the calculations of ##m^*_e## and ##m^*_h## are off by factors of 2.

Thanks. I'm not sure why he has added the term, and also he doesn't appear to have differentiated twice the energy at the beginning of the problem, he's just removed k. Very confusing answer to this question, but least I have the method now.
 
Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
