Hi student,

The correct answer for this question is option 3 that is F=3N,F=5N,F=6N.

Explanation:-

We know that the sum of these three forces is zero

For a triangle the sum of the two sides is always greater than the third side

Therefore, F1 = 3N; F2 = 5N; F3 = 6N

• F1 + F2 > F3
• F2 + F3 > F1
• F3 + F1 > F2

"Forces are in equilibrium when they form a triangle"

I hope this information helps you.

Good Luck!
