Answer:
h=32.1 km
Explanation:
<em>solution:</em>
using newton law of gravitational attraction and newton second law:
r= distance between two masses
at sea level
a=g
.............................(1)
.........................(2)
by substituting (2) and (1) acceleration due to gravity at a distance r from the centre of the earth in terms of g (sea level)
so the weight of the object at a distance r from the centre of the earth (W=ma)
W=mg(Re^2/r^2)..........(3)
h the height above the surface of the earth: r=Re+h
putting the value of r in eq (3)
W=mg(Re/Re+h)^2
W=0.99 mg
solving for height h:
h=Re(1/√0.99)-(1))
h=32.1 km
