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
Answer
Cannot keep the body in equilibrium
Explanation
Solution
If 1 N and 2 N act in the same direction and 3N acts in opposite direction, then equilibrium is possible.
