Lots of questions on propagating V3 so here’s the answer… I told some people incorrectly but will bot count off for that mistake. V 3 = (F/ μ ) 1/2 we need to apply a couple of rules for this one First we need to handle the stuff inside the ( ) Let x = F/ μ this is a division which is rule 3 So x /x = (( F/F) 2 +( ∆μ / μ ) 2 ) ½ Now ∆μ = 0 because it is a constant so the second term drops out x /x = (( F/F) 2 +0) ½ The square and the square root cancel each other so

Unformatted text preview: x /x = F/F Now back to the original equation V 3 = (F/ ) 1/2 lets rewrite this as V 3 = (x) 1/2 this falls under the power rule number 4 So v 3 /v 3 =[ (1/2)( x /x) 2 ] 1/2 Putting our Fs back in v 3 /v 3 =[ (1/2)( F /F) 2 ] 1/2 Then V 3 =V 3 *[ (1/2)( F /F) 2 ] 1/2 or I can expand it to V 3 =(F/ ) 1/2 [ (1/2)( F /F) 2 ] 1/2 Hope this helps!...
