At what the value of g would become one fourth than on the surface of theĩ. A polar satellite is launched at 850 km above Earth. The value of g is 4.0 ms-2 at a distance of 10000 km from the centre of the. due to the Earth at geostationary satemte. Calculate the value of g at a height of 3600 km above the surface of the Earth.Ħ. The acceleration due to gravity on the surface of moon is 1.62 ms-2ĥ. The mass of Mars is 6.42 x 1023 kg and its radius is 3370 km.Ĥ. Find the acceleration due to gravity on the surface of the Mars. The gravitational force between two identical lead spheres kept at 1 m apart isģ. The distance between the centers of the spheres is 0.5m.Ģ. Find the gravitational force of attraction between two spheres each of mass 1000 kg. The weight of the body of mass 10 kg on the surface of the moon:ġ. The gravitational force on the surface of the earth is equal to:Ģ4. The height of the Geostationary satellite above the surface of the earth is:Ģ3. If a rocket is fired vertically with a speed of-, it will start revolving. of Geostationary satellite with respect to earth is:Ģ1.An artificial satellite keeps on revolving around the earth in different orbits with uniform speed due to the?Ģ0. If the radius of the orbit is increased from R to 2R.
