what is the value of gravitational constant and its SI unit<\/p>\n\n\n\n
The correct answer and explanation is:<\/strong><\/mark><\/p>\n\n\n\n Correct Answer:<\/strong><\/p>\n\n\n\n The value of the gravitational constant is 6.674 \u00d7 10\u207b\u00b9\u00b9<\/strong> and its SI unit is m\u00b3\u00b7kg\u207b\u00b9\u00b7s\u207b\u00b2<\/strong>.<\/p>\n\n\n\n Explanation:<\/strong><\/p>\n\n\n\n The gravitational constant, often symbolized by the letter G<\/strong>, is a fundamental physical constant that appears in Newton’s law of universal gravitation. According to this law, every mass in the universe attracts every other mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.<\/p>\n\n\n\n Mathematically, Newton’s law is written as:<\/p>\n\n\n\n F = G \u00d7 (m\u2081 \u00d7 m\u2082) \/ r\u00b2<\/strong><\/p>\n\n\n\n Where:<\/p>\n\n\n\n In this equation, the gravitational constant G<\/strong> acts as a proportionality factor. Its value, 6.674 \u00d7 10\u207b\u00b9\u00b9<\/strong>, is very small. This indicates that the gravitational force is a relatively weak force compared to other fundamental forces like electromagnetism.<\/p>\n\n\n\n The SI unit of G<\/strong> is m\u00b3\u00b7kg\u207b\u00b9\u00b7s\u207b\u00b2<\/strong>. This unit is derived from the rearrangement of Newton\u2019s law of gravitation. Force has the unit of newtons (N)<\/strong>, which equals kg\u00b7m\/s\u00b2<\/strong>. When rearranged to isolate G<\/strong>, the resulting unit becomes m\u00b3\u00b7kg\u207b\u00b9\u00b7s\u207b\u00b2<\/strong>.<\/p>\n\n\n\n The gravitational constant is important in various scientific fields including astronomy, physics, and engineering. It allows scientists to calculate the gravitational forces between celestial bodies, the orbits of planets, and the behavior of satellites. It also plays a critical role in Einstein’s general theory of relativity, which extended Newtonian physics to account for phenomena involving very massive objects or high speeds.<\/p>\n","protected":false},"excerpt":{"rendered":" what is the value of gravitational constant and its SI unit The correct answer and explanation is: Correct Answer: The value of the gravitational constant is 6.674 \u00d7 10\u207b\u00b9\u00b9 and its SI unit is m\u00b3\u00b7kg\u207b\u00b9\u00b7s\u207b\u00b2.
