The value of "g" is _ in "Murree" than "Hyderabad":
Correct answer: A. Less
- A. Less
- B. Greater
- C. Same
- D. Equal
Explanation
The value of gravitational acceleration ( g ) varies with altitude. Near the surface of the Earth, the standard average value for ( g ) is approximately 9.8m/s2 However, as you move to different altitudes, the value of ( g ) changes due to the inverse square law of gravitation. Since Murree is at a higher altitude than Hyderabad, the value of g is comparatively lesser due to the inverse relationship between g and the distance from the center of the earth Rearth. As you move to higher altitudes, the distance Rearth from the center of the Earth increases, leading to a decrease in gravitational acceleration. This means that gravitational acceleration is slightly weaker at higher altitudes. The effect is more pronounced at greater distances from the Earth's surface, such as in space. However, for most practical purposes on or near the Earth's surface, ( g ) is often considered approximately constant at 9.8 m/s2.

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.
