Answer

Answer:

A. $\leftarrow30\ N$

Explanation:

Step1: Analyze the state of the box

The box is not moving, so it is in equilibrium.

Step2: Consider horizontal - direction forces

The pushing force is $30\ N$ to the right. For equilibrium in the horizontal direction, the frictional force must balance the pushing force.

Step3: Determine the frictional - force direction and magnitude

The frictional force acts in the opposite direction of the applied force. Since the applied force is $30\ N$ to the right, the frictional force is $30\ N$ to the left, which can be represented as $\leftarrow30\ N$.
