4P is the resultant according to the polygon law of forces but it should be in opposite direction.

I think polygon law is based on Vector only.

alright. vectors can be slid in a direction parallel to theirs. So, it would become

just what shayanreloaded drew. but if P is a variable and P-3P=-2P horizontal, 2P-4P=-2 vertical

Hi all....pls tell me why cant the resultant be simply zero..since when vectors are represented by the sides of a closed polygon taken in same order, the resultant is zero.
Pls help!!!!
