Question

stateband prove parallelogram law of vector addition​

Answer 1

Answer:

Parallelogram law of vector addition states that

if two vectors are considered to be the adjacent sides of a parallelogram, then the resultant of the two vectors is given by the vector that is diagonal passing through the point of contact of two vectors.

Proof:

Let  

A

 and  

B

 are the two vectors be represented by two lines  

OP

 and  

OQ

​  

 drawn from the same point. Let us complete the parallelogram and name it as OPTQ. Let the diagonal be   OT

.

Since   PT

 is equal and parallel to   OQ

​  

, therefore, vector   B

 can also be represented by   PT

.

Applying the triangle's law of vector to triangle OPT.

$OT = OP + PT ⇒ R = A + B .$
