Question

A space station is at a height equal to the radius of the Earth. If V E is the escape velocity on the surface of the Earth, the same on the space station is......times V E ., 1 2, 1 4, 1 2, 1 3

MARKS App · Accepted Answer

Escape velocity at a height h from the surface of Earth v E ′ = 2 G M R + h v E = 2 G M R Given, h = R ⇒ v E ′ = 2 G M R + R = 1 2 2 G M R = v E 2
