In a frictionless bowl shaped as a sphere, 4 identical balls of radius R and m assmare placed inside the bowl with their centers at the same levelled height. Then a fifth identical ball is placed on top of the 4 balls below and the balls can all remain in equilibrium. Required:
How much is the radius of the spherical bowl?
