SUMMARY
The correct answer for the static friction problem is 24.01 N, derived from the equation 0 = Fa - Ff, where Fa is the applied force and Ff is the frictional force. The frictional force (Ff) is calculated using the coefficient of friction (Mew = 0.245) and the normal force (Fn = 98 N), leading to Ff = 0.245 x 98. The discussion emphasizes the importance of understanding free body diagrams (FBD) in analyzing forces acting on the box, which remains stationary, confirming that acceleration (a) is zero.
