Answer 1

Answer:

at a) 5km the value of g is same as that of 10km more deep

Answer 2

$\huge\underline\mathbb{\red S\pink {0} \purple {L} \blue {UT} \orange {1}\green {ON :}}$

⇒ Let the variable "g" represent the height.

g = 0 ( 1- 2h/r ) - (1)

g = 0 ( 1- d/r) - (2)

⇒ The variable "d" represents the depth or also known as how deep.

g = 0 ( 1- 2h/r) - (1) ≡ g = 0 ( 1- d/r) - (2)

⇒ 2h/r = d/r

⇒ h =d/2 = 10/2 = 5 km

=>5km is answer.
