Question

What is the fnet of the 1st fbd on the left

Answer 1

400

Step-by-step explanation

Step 1

to know the net force, we need to add the forces ( vectors),so vertically we have

positive =1200 N

Negative = 800 N

so, the sum of vertical forces is

`\begin{gathered} \sum ^(\square)_{y-\text{foces}}=1200N-800N \\ \sum ^(\square)_{y-\text{foces}}=400\text{ N} \end{gathered}`

hence, the answer is 400 N
