The minimum and maximum distance of a satellite from the centre of earth are $2\mathrm{R}$ and $4\mathrm{R}$ respectively, where $\mathrm{R}$ is radius of earth, $\mathrm{M}$ is mass of earth, $\mathrm{m}$ is mass of satellite. Then choose the correct statement.

Radius of curvature at the point when it is at minimum distance from the centre of earth is $\frac{\text{8R}}{\text{3}}$

Total energy of satellite is $\frac{\text{GMm}}{\text{6R}}$

Minimum speed of satellite is $\frac{\text{GMm}}{\text{6R}}$

Angular momentum of satellite about centre of earth is $\sqrt{\frac{\text{8}}{\text{3}}{\text{GMRm}}^{\text{2}}}$
