Answer:

1)null vector is a vector having magnitude equal to zero. A null vector has no direction or it may have any direction. Generally a null vector is either equal to resultant of two equal vectors acting in opposite directions or multiple vectors in different directions.

2) If two vectors acting simultaneously on a particle are represented in magnitude and direction by the two adjacent sides of a parallelogram drawn from a point, then their resultant is completely represented in magnitude and direction by the diagonal of that parallelogram drawn from that point.

Answer:

Defination and proof of parallelogram:-

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 .

(proved).

Explanation:

Defination and example of null vactor

A null vector is a vector that has magnitude equal to zero and is directionless. It is the resultant of two or more equal vectors that are acting opposite to each other.

A most common example of null vector is pulling a rope from both the end with equal forces at opposite direction.

NOTE:-

IN IMAGE THE DIGRAM IS STANTS FOR PARALLELOGRAM.

THIS IS ONE AND LAST IMPORTANT NOTE:-
