Question

an artificial satellite is revolving in a circular orbit around the earth being around at the distance of 300 km above the earth's surface. calculate the velocity of the satellite (radius of the earth= 6400km, g=9.8 m/s²)
please give the solution​

Answer 1

Answer:

Orbital speed is given by, v=  

R+h

GM

Substituting the given values:

v=  

(6400+1200)×10
