Three concurrent co-planar forces \( 1 \mathrm{~N}, 2 \mathrm{~N} \) and \( 3 \mathrm{~N} \) acting along different directions on a body
(1) Can keep the body in equilibrium if \( 2 \mathrm{~N} \) and \( 3 \mathrm{~N} \)
P
act at right angle.
(2) Can keep the body in equilibrium if \( 1 \mathrm{~N} \) and \( 2 \mathrm{~N} \) act at right angle.
(3) Cannot keep the body in equilibrium
(4) Can keep the body in equilibrium if \( 1 \mathrm{~N} \) and \( 3 \mathrm{~N} \) act at an acute angle.
