Weight of a body of mass

m

at the Earth's surface,

W = m g = 250 N

Body of mass

m

is located at depth,

d = R_{e} /2

Acceleration due to gravity at depth

g (d)

is given by the relation:

g^{'} = (1 - \frac{d}{R _{e}}) g

g^{'} = (1 - \frac{R _{e}}{2 R _{e}}) g

= g /2

Weight of the body at depth

d

W^{'} = m g^{'}

= m g /2 = W /2

= 125 N
