Three equal masses of 1 kg each are placed at the vertices of an equilateral ΔPQR and a mass of 2kg is placed at the centroid O of the triangle which is at a distance of root 2 m from each of the vertices of the triangle. Find the force (in newton) acting on the mass of 2 kg.

A planet of radius R=1/10× (radius of Earth) has the same mass density as Earth. Scientists dig a well of depth R/5 on it and lower a wire of the same length and of linear mass density 10^−3kgm^-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 (take the radius of Earth =6×10^6m and the acceleration due to gravity on Earth is 10ms^−2)
