Answer 1

To maintain an object in a state of rest, the net force acting on it must be zero. This means that all the forces acting on the object must balance each other out.

Based on the information provided:

- Top force = 12 N (acting downwards)
- Right side force = 18 N (acting to the right)
- Left side force = 18 N (acting to the left)
- Bottom force = ? (acting upwards)

Let's analyze the forces:

1. The vertical forces need to balance:
- The downward force (from the top) is 12 N.
- The upward force (from the bottom) must also be 12 N to balance the downward force.

2. The horizontal forces also need to balance:
- The right horizontal force is 18 N.
- The left horizontal force is also 18 N, balancing the right force.

Since the top force is 12 N acting downwards, to keep the object at rest, an upward force of 12 N must be applied from the bottom.

Therefore, the force needed from the bottom is:

**12 N**
