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

A

can keep the body is equilibrium if 2N and 3N act at right angle

B

can keep the body is equilibrium if 1N and 2N act at right angle

C

cannot keep the body is equilibrium

D

can keep the body in equilibrium if 1N and 3 N act at an acute angle.

Text Solution

Verified by Experts

The correct Answer is:
C

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