A.none of the above
B.if a polygon representing forces acting at a point is closed then forces are in equilibrium
C.if any number of forces acting at a point can be represented by the sides
D.if any number of forces acting at a point can be represented in direction and magnitude by the sides of a polygon taken in order, then the forces are in equilibrium
E.if any number of forces acting at a point can be represented in direction and magnitude by the sides of a polygon, then the forces are in equilibrium
Explanation: The correct answer is if any number of forces acting at a point can be represented in direction and magnitude by the sides of a polygon taken in order, then the forces are in equilibrium.
