Assume the orbit to be circular. Takeradius of the earth as 6400 km and g at the surface of the earth to be 9.8 m/s2. ... Given: height of satellite above the surface of earth = h = 700 km, Radius of earth = R = 6400 km, G = 6.67 x 10-11 N m2/kg2 ; g = 9.8 m/s2.

Ya but what further
To find: speed of satellite = Vc = ?, period = T = ?
r = R + h = 6400 + 700 = 7100 km = 7.1 × 10 ki Power 6 m,
The speed of a satellite orbiting around the earth is given by
The time period of a satellite orbiting around the earth is given by
Ans: The speed of satellite is 7.519 km/s and period of revolution of the satellite is 5930 s.

Explanation:
total energy of satellite in orbit =kE+(-PE)
KE=1/2mv2
PE= -GMm/(R+h)
1/2mv²=GMm/(R+h)
v²= gR²/(R+h)
v =R(g/R+h)½
