Another one ~Mataa🫶🏽 — let's solve it. Step 1: Identify the forces involved and the conditions for equilibrium. To keep the box from falling, the upward static friction force (F_fr) must balance the downward gravitational force (mg). F_fr = mg The horizontal force (F) applied to the box creates a normal force (F_N) from the wall. Since the box is not moving horizontally, these forces are equal in magnitude. F = F_N The maximum static friction force is given by the formula: F_fr,max = _s F_N For the box to not fall, the static friction force must be at least equal to the gravitational force. The minimum applied force F corresponds to the situation where the static friction is at its maximum value. Step 2: Substitute the relationships into the static friction formula. We know F_fr = mg and F_N = F. Substitute these into the maximum static friction formula: mg = _s F Step 3: Solve for the minimum force F. Rearrange the equation to solve for F: F = (mg)/(_s) Step 4: Plug in the given values. Given _s = 0.40 and mg = 20 N: F = 20 N0.40 F = 50 N Step 5: Select the correct option. The calculated minimum force is 50 N, which corresponds to option (c). The final answer is c) 50 N. Send me the next one 📸
