Question

if your weight 60 kg on Earth how far must you go above the surface of earth so that you weight is 30kg​

Answer 1

Answer:

GO TO THE MOON SO OUR WIEGHT IS THE HALF OF OUR WEIGHT IN EARTH

Answer 2

Answer:

Till gravity becomes 4.9m/s^2 that is half of 9.8m/s^2.

g= GM/R^2

4.9= 6.67×10^-11 × 6×10^24 /R^2

R= 9,037,337.5165341 Km (thus radius of earth should be 9037337.5165341 Km to get mass as 30 kg)

Tangential Velocity = √(2GM/R+h)

By the above formula you can also find Height of object above surface of earth. If TANGENTIAL VELOCITY IS KNOWN.
