The weight of a body at earth's surface is $W$ . At a depth halfway to the centre of the earth, it will be (assuming uniform density in the earth) -

Options:

Answer:

Solution:

Due to depth $g^{'} = g \{1 - \frac{d}{R_{e}}\} ∴ d = R_{e} / 2$

so $g^{'} = g \{1 - \frac{R_{e} / 2}{R_{e}}\} = g / 2$

Now $g^{'}$ is half so weight is also half.
