Answer 2

$\boxed{\sf F_{net}=F_1+F_2\dots}$

Solution-1

• F1=8N
• F2=10N
• F3=-12N

$\\ \sf\longmapsto F_{net}=8N+10N-12N$

$\\ \sf\longmapsto F_{net}=18N-12N$

$\\ \sf\longmapsto F_{net}=6N$

Solution:-2

• F1=8N
• F2=-8N

$\\ \sf\longmapsto F_{net}=8N-8N$

$\\ \sf\longmapsto F_{net}=0N$

Solution:-3

• F1=8N
• F2=6N

$\\ \sf\longmapsto F_{net}=8N+6N$

$\\ \sf\longmapsto F_{net}=14N$

Solution:-4

• F1=9N
• F2=-8N

$\\ \sf\longmapsto F_{net}=9N-8N$

$\\ \sf\longmapsto F_{net}=1N$
