Q. Three concurrent co-planar forces $1\ N,\ 2\ N$ and $3\ N$ acting along different directions on a body
A) Can keep the body in equilibrium if $2\ N$ and $3\ N$ act at right angle
B) Can keep the body in$\ $equilibrium if $1\ N\ $and$\ 2\ N$ act at right angle
C) Cannot keep the body in equilibrium
D) Can keep the body in equilibrium if $1\ N$ and $3\ N$ act at an acute angle
Explanation
(c) If $1\ N$ and $2\ N$ act in the same direction and $3\ N$ acts in opposite direction, equilibrium is possible
