270573 The escape velocity of a body from earth surface is \(V_{e}\). The escape velocity of the same body from a height equal to \(7 R\) from earth surface will be

1 \(\frac{V_{e}}{\sqrt{2}}\)
2 \(\frac{V_{e}}{2}\)
3 \(\frac{V_{e}}{2 \sqrt{2}}\)
4 \(\frac{V_{e}}{4}\)

270574 Escape velocity of a body from the surface of the earth is \(V_{1}\) and from an altitude equal to twice the radius of the earth, escape velocity is \(V_{2}\). Then,

1 \(V_{1}=V_{2}\)
2 \(V_{1}=7 V_{2}\)
3 \(V_{1}=\sqrt{3} V_{2}\)
4 \(V_{1}=\sqrt{2} V_{2}\)
