Question

An artificial satellite is revolving round the earth at a height of 30 km above the surface of the earth. Find its orbital velocity.(R = 6370 km , g = 9.8 m/s2

Answer 1

Answer:

11200m/s or 11.2 km/s

Explanation:

h=30 km= 30000m

R= h+r

=30000+6370000

= 6400000m

V= √2gR

=√2×9.8×6400000

=√125440000

=11200m/s
