Question

find the percentage decrease in weight of a body when taken to a height of 16 kilometre above the surface of Earth​

Answer 1

Answer:

Explanation:

Percentage decrease in weight of body is 1%.

Solution:

Given: Height = 32 km

           Radius of the earth = 6400 km.

The formula to find the gravitational pull at a height above surface of earth is given by   

Rearranging the equation we get   

Therefore percentage decrease

On evaluating we get the percentage decrease in acceleration due to gravity is

As g is 1% less than , weight mg is also 1% less than .
