SUMMARY
The minimum force required to keep a 50kg block of wood in place against a smooth wall, given a coefficient of static friction of 0.13, is determined by balancing the frictional force with the gravitational force acting on the block. The correct approach involves setting the frictional force equal to the weight of the block, leading to the equation Ff = Fg. The frictional force is calculated using the formula Ff = µFn, where Fn is the normal force applied by the wall.
