Question

station 2
balanced and unbalanced forces
what is the net force acting on the box? what direction will it move?
a. 40 n to the right
b. 20 n to the right
c. 40 n to the left
d. 20 n to the left

Explanation:

Step1: Identify forces

There are two forces acting on the box: a $10N$ force to the right and a $30N$ force to the left.

Step2: Calculate net - force

Net force $F_{net}=F_1 - F_2$. Let the right - direction be positive. So $F_1 = 10N$ and $F_2=30N$. Then $F_{net}=10 - 30=- 20N$. The negative sign indicates the direction is to the left.

Answer:

D. 20 N to the left
