Respuesta :
We are given with 98 Newton weight of an object on the surface of the earth with an acceleration equal to 9.8 m/s2. This means the mass of the object is equal to 98/9.8 or 10 kg. Hence the weight of the object 10,000 kilometers above sea level where acceleration is 1.49 m/s2 is 14.9 Newtons.
Answer:
14.90 Newtons
Explanation:
As we know the formula for Force = m×g
where F is force applied on the mass by gravity, m is the mass and g = 9.8 m/sec² at the Earth.
Since F = 98 newton
g = 9.8 [tex]\frac{\text{meter}}{\text{sec}^{2} }[/tex]
So by putting this value in the formula we can calculate the mass of the object
98 = 9.8×m
m = [tex]\frac{98}{9.8}=10[/tex] kg
Now we have to calculate the weight of the object at a point 10000 kilometers above the sea level where g becomes 1.49 [tex]\frac{\text{meter}}{\text{sec}^{2} }[/tex]
By putting these values in the formula again
F = 10×1.49 = 14.90 Newton
Therefore, weight of the object will be = 14.90 newton.
