Which of the following sets of concurrent force may be in equilibrium?

Options

A. `F_(1)=3N, F_(2)=5N, F_(3)=1 N`
B. `F_(1)=3N, F_(2)=5N, F_(3)=6 N`
C. `F_(1)=3N, F_(2)=5N, F_(3)=9 N`
D. `F_(1)=3N, F_(2)=5N, F_(3)=16 N`

Answer

B

Explanation

For equilibrium, net resultant for must be zero. These forces form a closed traingle such that
`F_(1)~F_(2) le F_(3)le F_(1)+F_(2)rArr 2N le F_(3) le 8N`
