Two satellites P and Q are moving in different circular orbits around the Earth (radius $\mathrm{R}$). The heights of P and Q from the Earth surface are ${\mathrm{h}}_{\mathrm{P}}$ and ${\mathrm{h}}_{\mathrm{Q}}$ respectively, where ${\mathrm{h}}_{\mathrm{P}}=\frac{\mathrm{R}}{3}.$ The accelerations of P and Q due to Earth’s gravity are ${\mathrm{g}}_{\mathrm{P}}$ and ${\mathrm{g}}_{\mathrm{Q}}$,  respectively. If $\frac{{\mathrm{g}}_{\mathrm{P}}}{{\mathrm{g}}_{\mathrm{Q}}}=\frac{36}{25}$ what is the value of ${\mathrm{h}}_{\mathrm{Q}}$ ?
