Answer 1

Explanation:

$\huge\underline\mathfrak\color{pink} Answer$

weight of body on the surface of the earth, W = 2000N

so, mass of body = W/g , where g is acceleration due to gravity on the surface of the earth. i.e., g = 10m/s²

now, m = 200/10 = 20 Kg.

find acceleration due to gravity d m depth from the surface of the earth.

we know,

$g'= 1 - \frac{d}{r}$

$given, d = R/2$

$so, g' = g(1 - 1/2) = g/2 = 5m/s²$

now weight of body = mg'

$so, g' = g(1 - 1/2) = g/2 = 5m/s²$

= 20 × 5 = 100N

$so, g' = g(1 - 1/2) = g/2 = 5m/s²$

$hence, \: answer \: is \: 100 \: N.$
