Question
Looking at the total net force on the boy sitting on the chair, are the forces balanced or unbalanced? Why? square opposite directions balanced because the boy and the chair have equal forces in square the same direction balanced because the boy and the chair have equal forces in unbalanced because the chair has a greater force Rewatch

Answer
The forces are balanced because the boy and the chair have equal forces in opposite directions.
Explanation
## Step 1: Understand the scenario. We have a boy sitting on a chair. We need to determine if the forces acting on the boy are balanced or unbalanced.## Step 2: Consider the forces acting on the boy. The boy exerts a force on the chair due to his weight (downwards), and the chair exerts an equal and opposite force on the boy (upwards). This is according to Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.## Step 3: Evaluate the options. The first statement says the forces are balanced because the boy and the chair have equal forces in opposite directions. This is correct, as explained in step 2. The second statement is incorrect because the forces are not in the same direction. The third statement is incorrect because the chair does not exert a greater force on the boy; the forces are equal.### The formula used in this problem is Newton's third law of motion: **
