when we place a coin on top of a table it is balanced because the line connecting the centre of mass and the ground pass though the point which is within the base of the coin.But if start stacking the same type of coins beyond a point it is unstable and this depends on the diameter of the coin.My doubt here is when we stack similar coins the combined centre of mass shd still be on the same initial line.Then why shd the stack of coins collapse beyond a particular no of coins stacked?
