Question 13 1 pts 1. Bertrand's theorem says: a) for every force, there is at least one orbit that is not closed b) the only forces for which all orbits are closed are the 1/r2 and -kr forces c) for forces other than 1/r- and -kr, there are no closed orbits Od) gravitational forces and centrifugal forces always exactly balance balance for at least one orbit e) the orbits in inverse square laws are ellipses O fb and
