Question

What is the value of acceleration due to gravity at an altitude of 500km? The radius of the earth is 6400 km

Answer 1

8.45 m/s square pls mark as braniliest

Answer 2

Given : d=1600km R=6400km

Acceleration due to gravity at a depth d, g

d

=g

s

(1−

R

d

)

where g

s

=9.8ms

−2

is acceleration due to gravity at earth's surface.

∴ g

d

=9.8(1−

6400

1600
