(i) State the associative and commutative laws of vector addition.
(ii) For two given vectors `A=hat I + 2 hat j -3hat k , overset(rarr)B=2 hati -hat j + 3 hatk` find the vector sum of `overset(rarr)A` and `overset(rarr)B` also find the magnitude of `(overset(rarr)A+overset(rarr)B)`

Explanation

### Step-by-Step Solution:

#### (i) State the Associative and Commutative Laws of Vector Addition

1. **Associative Law of Vector Addition**:
The associative law states that when adding three vectors, the way in which the vectors are grouped does not affect the sum. Mathematically, this can be expressed as:
\[
\vec{A} + (\vec{B} + \vec{C}) = (\vec{A} + \vec{B}) + \vec{C}
