$<font color = "green"><marquee > hi mate......!!!!</font color = "green"></marquee>$

polygon law of vectors states that if a number of vectors are represented both in magnitude and direction by the open sides of a polygon taken in the same order then the resultant vector is represented both in magnitude and direction by the closing side of the polygon taken in opposite order .

Answer 2

If a number of vectors are represented by both in magnitude and direction by the sides of an open polygon taken in same order, then their resultant is represented both in magnitude and direction by the closing side of the polygon taken in opposite order.
