Question

Polygon law of vector addition how to exicute it

Answer 1

Answer:

• The polygon law of vectors is used for addition of more than two vectors STATEMENT: If number of vectors are represented in magnitude and direction by the sides of an incomplete polygon taken in order their resultant is represented by magnitude and direction of remaining sides of polygon taken in opposite order

Explanation:

1. Let vectors P,Q,S,T are represented by four sides of incomplete polygon taken as AB,BC,CD,and DE respectively as shown in fig According to polygon law of vector addition remaining side AE of the polygon taken in opposite order will represent the resultant R which is given by R=P+Q+S+T PROOF: In triangle ABC according to triangle law of vector addition AC=AB+BC AD=P+Q IN triangle ACD AD=AC+DC AD=P+Q+S IN TRIANGLE ADE AE=AD+DE AD=P+Q+S+T

Answer 2

Answer:

heya

Polygon law of vector addition states that if a number of vectors can be represented in magnitude and direction by the sides of the polygon taken in the same order,then their resultant is represented in magnitude and direction by the closing side of the polygon taken in the opposite order.
