Q25. A geostationary satellite orbits around the earth in a circular orbit  of radius 36000 km. Then the time period of a satellite orbiting a few hundred kilometres above the earth's surface (  R E a r t h = 6400 km) will approximately be:

A. 1/2 h

B. 1 h

C.  2 h

D. 4 h

Dear Student,

As we know that time period of a sattelite very close to earth surface is 84.6 minutes ...also time period increases due to increase in distance so time period of spy sattelite must be slightly greater than 84.6 minutes so most appropriate answer is 2 hours
