Q1: A satellite is said to move in a synchronous orbit if it moves at an altitude of 36, 000 km with a maximum velocity of about

ANS:E - 11,000 km per hour

A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period (24 hours). Such a satellite returns to the same position in the sky after each sidereal day, and over the course of a day traces out a path in the sky so T=24 hours.

Distance covered by any satellite = (radius of the earth+traveling distance by satellite)*2*3.14.
=(6,371 km+36000)x2x3.14.
=266089.88 km.
Velocity= distance/time.
= 266089/24.
= 11,087 km/hr.

Says 11000 km/hr.
