Which of the following sets of concurrent forces may
be in equilibrium ?
(1) F1
= 3N, F2
= 5N, F3
= 1N
(2) F1
= 3N, F2
= 5N, F3
= 9N
(3) F1
= 3N, F2
= 5N, F3
= 6N
(4) F1
= 3N, F2
= 5N, F3
=15N

Answer:
C
Explanation:
According to the triangle law in forces, resultant of given forces, sum of any two forces is greater than or equal to the third force.
Case A:F1+F3<F2...... cannot be in equilibrium
Case B: F1 + F2<F3..... cannot be in equilibrium
Case D : F1+F2<F3 ...... cannot be in equilibrium
Case C : F1+F2>F3; F1+F3>F2; F3+ F2>F1
only case c is following the required criteria.
