Final answer:
An unbalanced force occurs when the forces acting on an object are not equal and opposite, causing a change in the object's motion. This is dictated by Newton's second law of motion. When forces are balanced, the object remains at rest or continues its motion unchanged.
Explanation:
An unbalancedforce refers to a scenario in which the forces acting on an object are not equal in magnitude and direction, causing a change in the motion of the object. In accordance with Newton's second law of motion, the motion change is directly proportional to the total unbalanced force and occurs in the direction of that force. Exceptionally, if the forces acting on an object are balanced, the object will either stay at rest or continue moving with a constant velocity, since the net force equals zero.
Consider this simple example to illustrate the principle. If you push a table to the right with a force of 10 Newtons and nothing pushes back with an identical force, the unbalanced force causes the table to move to the right. This is because there is an unbalanced force exerted upon it. Conversely, if an equal force of 10 Newtons is applied to the table from the opposite direction, these forces are balanced, and the table remains stationary because the net force is zero.

The smallest value of the force that will make the block not to slide down is 10 N.
We'll begin by calculating the normal reaction. This can be obtained as follow:
- Mass (m) = 8 Kg
- Acceleration due to gravity (g) = 10 m/s²
- Normal reaction (N) =?
N = mg
N = 8 × 10
N = 80 N
Finally, we shall determine the frictional force.
- Coefficient of friction (μ) = 0.4
- Normal reaction (N) = 80 N
- Frictional Force (F) =?
F = μN
F = 0.4 × 80
F = 32 N
Since the frictional force is 32 N, therefore, a force lesser than the frictional force will make the blocknot to slide down.
From the options given above, only option A has a force that is lesserthan the frictional force.
Therefore, the correct answer to the question is Option A. 10 N

Final answer:
The smallest value of the force that will not slide the 8.0 kg block down the wall is 31.36 N.
Explanation:
To determine the smallest value of the force such that the 8.0 kg block will not slide down the wall, we need to consider the static friction between the block and the wall. The formula for static friction is fs = μs * N, where μs is the coefficient of static friction and N is the normal force. In this case, the normal force is equal to the weight of the block, which is mg = 8.0 kg * 9.8 m/s^2 = 78.4 N. Therefore, the smallest value of the force is equal to the maximum static friction force, which can be calculated as fs = 0.4 * 78.4 N = 31.36 N. So the correct answer is 31.36 N.
