The Earth is assumed to be a sphere of radius R. A platform is arranged at a height R from the surface of the Earth. The escape velocity of a body from this platform is \(f v_{r}\), where νe is its escape velocity from the surface of the Earth. The value of \(\text { f }\) is:
- \(\sqrt{2}\)
- \(\frac{1}{\sqrt{2}}\)
- \(\frac{1}{3}\)
- \(\frac{1}{2}\)
