The ratio of orbital velocoty to escape velocity is
2 Answers
Amritpal Singh Saini
Orbital velocity is given by √gR , where R is the radius of earth and escape velocity is given by √2gR Thus the ratio of orbital velocity to escape velocity is 1/√2 (or 0.7070)

Orbital speed at the surface is given by
GM/R^2 = V^2 / R
V = √ G M / R
For escape velocity
1/2 . m . V(e)^2 = GMm / R
V(e) = √ 2 . G . M / R
V(e) / V = √2
( This is the same for any satellite around any planet or star )

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
