Part A: Period of a Geosynchronous Satellite<\/strong><\/h3>\n\n\n\nTo find the period ( T ) of a satellite in a geosynchronous orbit<\/strong>, we recognize that such a satellite must orbit the Earth once every 24 hours<\/strong>, to remain over the same spot on the equator.<\/p>\n\n\n\nBut we convert this to seconds:<\/p>\n\n\n\n
[
T = 24 \\, \\text{hours} \\times 3600 \\, \\text{seconds\/hour} = \\boxed{8.64 \\times 10^4 \\, \\text{s}}
]<\/p>\n\n\n\n
\n\n\n\nPart B: Gravitational Acceleration ( g ) at the Altitude<\/strong><\/h3>\n\n\n\nWe use the formula for gravitational acceleration at a distance ( r ) from the center of the Earth:<\/p>\n\n\n\n
[
g = \\frac{GM}{r^2}
]<\/p>\n\n\n\n
Where:<\/p>\n\n\n\n
\n- ( G = 6.674 \\times 10^{-11} \\, \\text{m}^3\/\\text{kg} \\cdot \\text{s}^2 )<\/li>\n\n\n\n
- ( M = 5.972 \\times 10^{24} \\, \\text{kg} )<\/li>\n\n\n\n
- ( r = R_{\\text{Earth}} + h = 6.371 \\times 10^6 \\, \\text{m} + 3.58 \\times 10^7 \\, \\text{m} = 4.217 \\times 10^7 \\, \\text{m} )<\/li>\n<\/ul>\n\n\n\n
Now plug in:<\/p>\n\n\n\n
[
g = \\frac{6.674 \\times 10^{-11} \\cdot 5.972 \\times 10^{24}}{(4.217 \\times 10^7)^2}
= \\boxed{0.224 \\, \\text{m\/s}^2}
]<\/p>\n\n\n\n
\n\n\n\nPart C: Weight of a 2000 kg Satellite<\/strong><\/h3>\n\n\n\nWeight ( W ) is given by:<\/p>\n\n\n\n
[
W = mg = 2000 \\, \\text{kg} \\cdot 0.224 \\, \\text{m\/s}^2 = \\boxed{448 \\, \\text{N}}
]<\/p>\n\n\n\n
\n\n\n\nExplanation (300 words)<\/strong><\/h3>\n\n\n\nGeosynchronous satellites are essential for consistent communication because they appear stationary from the Earth’s surface. To achieve this, they must orbit at the same rotational rate as Earth\u2014once every 24 hours. This gives the satellite a period<\/strong> ( T ) of 86,400 seconds.<\/p>\n\n\n\nThe altitude for such an orbit is about 35,800 km above Earth\u2019s surface. However, to calculate gravitational effects like ( g ), we need the distance from the Earth\u2019s center<\/strong>, which is the sum of Earth\u2019s radius and the satellite\u2019s altitude. The gravitational force decreases with distance from Earth\u2019s center, so ( g ) is smaller at this height compared to Earth\u2019s surface. Using Newton’s Law of Universal Gravitation, we calculate ( g ) at that distance to be approximately 0.224 m\/s\u00b2\u2014far less than the 9.81 m\/s\u00b2 we experience on the surface.<\/p>\n\n\n\nWeight is the gravitational force acting on an object. So, for a satellite with a mass of 2000 kg, its weight in orbit is the product of mass and the weaker gravitational field: ( 2000 \\times 0.224 = 448 \\, \\text{N} ). While this is much less than its Earth-surface weight (which would be 19,620 N), it still experiences some gravitational pull, which is why it remains in orbit rather than flying off into space.<\/p>\n\n\n\n
Even though the satellite is “weightless” in the sense that it is in free fall, it’s still under the influence of gravity. This is key to orbital motion\u2014it’s the continuous “fall” around the Earth that maintains its circular path.<\/p>\n\n\n\n![\"\"](\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/04\/image-82.png\")
