Question

Three concurrent co-planer forces 1N, 2N and 3N acting along different directions on a body.

• A. Can keep the body in equilibrium if 2N and 3N act at right angle.
• B. Can keep the body in equilibrium if 1N and 2 N act at right angle
• C. Can keep the body in the equilibrium.
• D. Can keep the body in equilibrium if 1N and 3N act at an acute angle.

Answer 1

Answer: (C)

Can keep the body in the equilibrium.

If 1 N and 2 N act in the same direction and 3N acts in opposite direction, then equilibrium is possible.
