Two boys stretch the dynamometer in opposite directions Each applies a force of 50 N. What value will the dy- namometer show? Answer: __ H.

## Step 1<br />The problem involves two boys opposite directions. The forces applied by both boys are equal, which is 50 N each.<br /><br />## Step 2<br />When forces are applied in opposite directions, they cancel each other out. This is because the force applied by one boy is equal and opposite to the force applied by the other boy.<br /><br />## Step 3<br />Since the forces cancel each other out, the net force acting on the dynamometer is zero. This is because the sum of the forces applied by the two boys is zero.<br /><br />## Step 4<br />The dynamometer measures the net force acting on it. Since the net force is zero, the dynamometer will show zero.
