Question

problem net force equation (include direction of force & label) balanced or unbalanced? (circle answer) 1 50 n right and 100 n left 100 - 50 = 50n balanced unbalanced 2 7n 10n 10 - 7 = 2n left balanced unbalanced 3 left right 7n 7n balanced unbalanced

Explanation:

Step1: Calculate net - force for problem 1

Net force $F_{net1}=100 - 50=50$ N (left). Since net force is non - zero, it is unbalanced. The correct net - force equation should be $F_{net1}=100N - 50N = 50N$ (left).

Step2: Calculate net - force for problem 2

Net force $F_{net2}=10 - 7 = 3$ N (right). The given equation $10 - 7=2$ N (left) is incorrect. Since net force is non - zero, it is unbalanced.

Step3: Calculate net - force for problem 3

Net force $F_{net3}=7 - 7=0$ N. Since net force is zero, the forces are balanced.

Answer:

1. Net Force Equation: $100N - 50N = 50N$ (left), Unbalanced
2. Net Force Equation: $10N - 7N = 3N$ (right), Unbalanced
3. Net Force Equation: $7N - 7N = 0N$, Balanced
