Question

A satellite is revolving just near the Earth's surface. calculate its orbital velocity given that radius of earth 6400 kilometre and G 9.8 ms.​

Answer 1

Answer:

Approx, 8 Km/Sec.

Explanation:

The orbital velocity of satellite near the earth surface is

v0 = root of (g*Re)

g=9.8m/sec2,

Re=6.4×10 power 6 metre

V0 =7.92×10 cube m/sec=7.92km/sec.
