Question

At what height above the planet's surface would a spaceship need to be located to remain in a geosynchronous orbit around Mars? [Mars has a radius of about 2100 miles and a mass of about 6.4 x 1023 kg. Mars rotates abouts its own axis about once every 24.6 hours. In other words one 'sol' is 24.6 hours.

] a. 10,600 miles b. 8500 miles c. 12,700 miles d. 17,000 miles

Answer 1

At what height above the planet's surface would a spaceship need to be located to remain in a geosynchronous orbit around Mars?

So the orbit is circular and in a circular orbit, gravitational force experienced by the satellite is equal to the centripetal force.

Where M_m is mass of Mars, m_s is mass of satellite and R is the orbit radius
