The weight of an object decreases as we go higher above the surface of Earth. explain why?
Solution
We know that weight of a body is the force with which the body is attracted towards the center of earth.
W = m × g
Where, m = Mass of the body And, g = Acceleration due to gravity
The mass of a body or object is constant and does not change from place to place. But acceleration due to gravity is inversely proportional to the square of the distance from the center of earth. So, as we go up from surface of the earth, the distance from the center of earth increases and hence value of g decreases.
Since, W = m × g
So, as the g decreases, weight of the body also decreases with increase in height above the earth.
Thus, as we go higher above the surface of the earth the weight of the body decreases
