Hi guys welcome you all to this new video covering the topic i.e. Problem:- Calculate the height of a geostationary satellite from the surface of the earth? Now if the height of the satellite (h) from the surface of the earth is negligible with respect to the Radius of the earth, then we can write r=R+h = R (as h is negligible). Go back to subject. The concept of a geostationary … Two stars each of one solar mass (= 2 x 10, kg) are approaching each other for a head-on collision. According to the law of conservation of momentum, According to the law of conservation of energy, We have Mass of the star, Distance between the stars, Radius of star, The distance between two stars when they collide is, 2r = 2 x 107m∴ Speed with which the stars collide is given by, 232, Block C-3, Janakpuri, New Delhi, Since the earth's surface is 6.37 x 10 6 m from its center (that's the radius of the earth), the satellite must be a height of. A geo-stationary satellite is a particular type used in television and telephone communications. Similarly gravitational field due to mass M. Since the net gravitational field at P is zero, therefore, object placed at P will be in equilibrium and the equilibrium is unstable equilibrium. Now if the height of the satellite (h) from the surface of the earth is negligible with respect to the Radius of the earth, then we can write r=R+h = R (as h is negligible). Where R= distance of satellite from the earth. 0-000-000-0000 Sec 5, Noida, Uttar Pradesh, India . 5 R from the surface of earth in hours is The above derivation gives the height of the Geostationary orbit.
