Question

A mass of 20 kg is taken to a height of 160 km above the
earth’s surface Earth’s radius is about 6370 km What is
the mass of the object at that height? How much does the object
weigh at this height? Radius of earth R = 6400 km

Dear Student,

mass, m=20 kgradius of earth, r=6370 kmheight above earth, h=160 kmg=10 m/s2Mass of object remains constant
 therefore, mass=20 kgWeight=mrr+h2gWeight=2063706370+1602×10Weight=0
19 kN

A mass of 20 kg is taken to a height of 160 km above the earth’s surface. Earth’s radius is about 6370 km. What is the mass of the object at that height? How much does the object weigh at this height? Radius of earth R = 6400 km.
