Question

Find the reletion between height and depth, when ,g1 and g equal.
please give me the right answer
​

Answer 1

Answer:

Let the radius of the earth be R and acceleration due to gravity at earth surface be g.

Acceleration due to gravity at height h above the earth surface, g

h

=g(1−

R

2h

)

Acceleration due to gravity at depth d below the earth surface, g

d

=g(1−

R

d

)

Now for g

h

=g

d

we get, g(1−

R

2h

) =g(1−

R

d

)

⇒ 1−

R

2h

=1−

R

d

⇒ d=2h
