Question

Find the weight of an object at a height 6400 km above the Earth's surface. The weight of the object at the surface of the Earth is 20N and and the radius of the earth is 6400 km.​

Answer 1

Answer:

5n

Explanation:

g(h) = g{r/r+h}^2

g(h) = 9.8 . {6400/6400+6400}^2

g(h) = 9.8 . (0.5)^2

g(h) = 9.8 × 0.25

g(h) = 2.45

weight of the body equals to Mg....

mass = 20N/9.8 = 2.04kg

g(h) equals to 2.45

weight equals to 2.04×2.45 = 5N
