Question

an artificial satellite is moving in a circular orbit of radius 32000 km if if it takes 30 hours to complete one Revolution around the earth then find the velocity of the satellite

Answer 1

we have given ,
radius of circular orbit , r = 32,000 km
Time taken to complete one revolution around the earth, T = 30 hrs

we know, formula
$v=\frac{2\pi r}{T}$
v = 2 × 22/7 × 32,000/30 km/hr
= 44/7 × 3200/3
= 44 × 3200/21 km/hr
= 6704.76 km/hr

$\textbf{hence, velocity of the satellite = 6704.76 km/h}$
