359659 The ratio of the accelerations due to gravity at the bottom of a deep mine and that on the surface of the earth is 978 / 980 . Find the depth of the mine, if the density of the earth is uniform throughout and the radius of the earth is 6300 $\mathrm{km}$.

359660 Assuming the earth to be a sphere of uniform mass density, how much would body weight half way down to the centre of earth if it weighted 250 $N$ on the surface?

359661 Scientists dig a well of depth ${\displaystyle \frac{R}{5}}$ on earth and lower a wire of the same length and of linear mass density ${10}^{-3}kg{m}^{-1}$ into it. If the wire is not touching anywhere, the force applied at the top of the wire by a person holding it in place is (radius of earth $=6\times {10}^{6}m$, acceleration due to gravity of earth is $10m{s}^{-2}$)

359658 An object is placed at a distance of $R/2$ from the centre of earth. Knowing mass is distributed uniformly, acceleration of that object due to gravity at that point is: ( $g=$ acceleration due to gravity on the surface of earth and $R$ is the radius of earth)
