Answer:
<em>The weight is 348.4 N</em>
Explanation:
<u>Effect of the Altitude on the Acceleration of Gravity</u>
The effect of gravity decreases with altitude because greater altitudes mean greater distances from the Earth's center.
The practical formula to calculate the gravity as a function of the altitude h is:
Where go is the conventional gravitational acceleration =
R is the Earth's mean radius at the equator = 6,378 Km
h is the altitude.
At a height of h=800 Km, the acceleration of gravity is:
Calculating:
The weight is the product of the acceleration of gravity by the mass of the object, thus:
The weight is 348.4 N
