Question

What is position vector and triangle law of vector addition ?

Answer 1

Hey.....!!.^_^


Here's ur ans.



============

➡ POSITION VECTOR -- It represents position of an point or particle . The arrow joining origin to that point or particle geometrically represents position vector .


For eg. -- If coordinate of point P is (3,4) position vector will be 3i cap + 4 j cap




➡ TRIANGLE LAW OF VECTOR ADDITION --- If two sides of a triangle represents vector A and B taken in same order then third side of the triangle taken in opposite direction represents sum of this two vectors .

Answer 2

Triangle law of Vactor Addition
-------------------------------------
Triangle law of Vector Addition stated that when two vectors are represented by two sides of a triangle in magnitude and direction, then they were taken in the same order and the third side of that triangle represents in magnitude and direction.

In short, if you have two vectors that represent the two sides of the triangle then the third side of that triangle will represent their resultant.

1) This is the law which is mainly used in engineering works


 2) This law was stated in the 18th century
