Question

Calculate value of acceleration due to gravity inside earth depth equal to half the radius?​

Answer 1

Explaination:

g = Gm/r²

If we take r = r/2

Then,

g = Gm/(r/2)

g = Gm/ r²/4

gr² = 4Gm -----------(1)

put Gm = gr²/4

g = gr²/4 / r²

gr² = gr²/4

g = g/4

g = 4g

Proved

And g is inversely proportional to r²

when radius of earth decrease then acceleration due to gravity increases.
