							here equate centrifugal force and gravitational force with question condition$mr\omega ^{2}=G\frac{m_{1}m_{2}}{r^{\frac{3}{2}}}$assume Gm1m2 = k constant$mr\omega ^{2}=kr^{-\frac{3}{2}}$now $\omega ^{2}=\frac{k}{m}r^{-\frac{5}{2}}$now put the value of omega$\omega =\frac{2\pi }{T}$and simplify the equation$\frac{4\pi ^{2}}{T^{2}}=\frac{k}{m}r^{-\frac{5}{2}}$remove constants from the equation${T^{2}}\propto r^{\frac{5}{2}}$so x = 5/2
