You should use equations (3.88) on page 54 but replace the equation for G with the equation for [itex]\alpha'[/itex]. Then follow the technique on that page.ehrenfest said:Is there another equation I should use?
There are three equations labeled (3.88). Replace all of the P subscripts with S. Toss out the equation that defines G and use equation (8.63) in its place. Express [itex]\sqrt{\alpha'}[/itex] in terms of [itex]{l}_S, {m}_S,[/itex] and [itex]{t}_S[/itex].ehrenfest said:Sorry, can you explain what you mean replace the equation for G with the equation for alpha' (8.63 I assume)? G and J/hbar do not even have the same units.
