Egrav and r are related by the equation Egrav=GmM/r where all the other quantities in the equation are constant. Which two of the following graphs would be straight lines going through the origin?
Egrav against r
r against E^2grav
r against 1/Egrav
1/Egrav against 1/r
Egrav against r^2
Egrav against 1/r

Good conceptual question - sketch the curves and see if (0,0) falls on any of those curves.
