Three identical steel balls, each of mass m=85kg, are placed in the cylindrical ring which rests on a horizontal surface and whose height is slightly greater than the radius of the balls. The diameter of the ring is such that the balls are virtually touching one another. A fourth identical ball is then placed on top of the three balls. Determine the force P (in N, roundoff to 2 decimal places exerted by the ring on each of the three lower balls.
