The escape velocity from an altitude equal to radius of the Earth above Earth's surface is:
$($ Escape velocity from surface of the Earth is $11.2$ kms $^{- 1}$ $)$
$2.8 k$ ms $^{- 1}$
$5.6$ kms $^{- 1}$
$11.2$ kms $^{- 1}$
$7.92$ kms $^{- 1}$

Escape speed is $v_{e} = \sqrt{\frac{2 G M}{R}} = 11.2$ km/s on Earth's surface.
Escape speed from an altitude $R$ from Earth's surface that is $2 R$ distance from the centre of Earth, is
$v_{e}^{^{'}} = \sqrt{\frac{2 G M}{2 R}} = 11.2 \times \frac{1}{\sqrt{2}} = 7.919$ km/s

The escape velocity from an altitude equal to radius of the Earth above Earth's surface is:( Escape velocity from surface of the Earth is 11.2 kms−1 )2.8k ms−15.6 kms−111.2 kms−17.92 kms−1

Escape speed is ve=√2GMR=11.2 km/s on Earth's surface.Escape speed from an altitude R from Earth's surface that is 2R distance from the centre of Earth, is v′e=√2GM2R=11.2×1√2=7.919 km/s

Escape speed is $v_{e} = \sqrt{\frac{2 G M}{R}} = 11.2$ km/s on Earth's surface.
Escape speed from an altitude $R$ from Earth's surface that is $2 R$ distance from the centre of Earth, is
$v_{e}^{^{'}} = \sqrt{\frac{2 G M}{2 R}} = 11.2 \times \frac{1}{\sqrt{2}} = 7.919$ km/s
