Application +4 | -1

An artificial satellite is moving in a circular orbit around the earth with a speed equal to half the magnitude of escape velocity from the earth. If the satellite is stopped in its orbit and allowed to fall freely onto the earth, the speed with which it hits the surface _____

\mathrm{km} / \mathrm{s}.

[g=

9.8 \mathrm{~ms}^{-2}

and

\left.{R}_e=6400 \mathrm{~km}\right]

View answer and explanation

Correct option: A

7.92

Option A (T) is correct because the period depends on the density of the planet, and since the density is the same, the period remains the same.
