Step 1

(1)

Consider the mass of the box be m as a unit mass that is 1 kg, the angle of 6 N force from the horizontal be θ.

Apply Newton’s second law of motion along the horizontal on the box, consider both the forces are at 45o, and solve for the acceleration of the box given in the first diagram.

Step 2

(2)

Here, both the forces are perpendicular to each other, so the angle between these forces are 90o. Apply Newton’s second law of motion along the horizontal on the box, and solve for the acceleration of the box given in the second diagram.

Step 3

(3)

Here, both the forces are in same direction, so the angle between these forces is 0o. Thus, apply Newton’s second law of motion alo...
