[#300] The Law of Polygon of Forces states that

(A) If a polygon representing the forces acting at point in a body is closed, the forces are in equilibrium

(B) If forces acting on a point can be represented in magnitude and direction by the sides of a polygon taken in order, then the resultant of the forces will be represented in magnitude and direction by t

(C) If forces acting on a point can be represented of a polygon taken in order, their sides of a polygon taken in order, their resultant will be represented in magnitude and direction by the closing side

(D) If forces acting on a point can be represented in magnitude and direction by the sides of a polygon in order, the forces are in equilibrium

Correct Answer

(C) If forces acting on a point can be represented of a polygon taken in order, their sides of a polygon taken in order, their resultant will be represented in magnitude and direction by the closing side
