Question

explain triangle law of addition

Answer 1

♠ ANSWER :

❇ VECTOR LAW OF TRIANGLE ADDITION

❇ It states that if two vectors can be represented both in magnitude and direction by the two sides of a triangle taken in the same order, then their resultant is represented completely, both in magnitude and direction, by the third side of the triangle taken in opposite order.

Answer 2

Statement of triangle law.

If 2 vectors acting simultaneously on a body are represented both in magnitude and direction by 2 sides of a triangle taken in an order then the resultant of these vectors is given by 3rd side of that triangle taken in opposite order ...


DERIVATIONS OF THE LAW.

Consider two vectors P and Q acting on a body and represented both in magnitude and direction by side OA and AB respectively of a triangle OA. Let ○ be the angle between P and Q , Let R be the resultant of the vectors P and Q. Then according to triangle Law of vector addition, side OB represent the resultant of P and Q. .
