Question

what is the time period when a satellite orbiting very near to the surface of the earth in a circular path (g=10m/s2)(radius= 6400 kilometre)​

Answer 1

Answer:

Explanation:

Time peroid of a satalite very close to earth surface

First orbital speed Vo=√gR

Vo=circumference of orbit (take h≈0) / peroid of revolution

   Vo  =2πR/ T

     T  =2πR/Vo

         =2πR/√gR

          ≈85 minutes
