Question

Represent the following vector and find their magnitude.
(I) A = Î + J cap
(ii) B = 3Î + 3J cap
(iii) C = 3Î + J cap
(iv) D = √3 î + J cap
(v) E = √2î + √2 J cap
(vi) (√3 + 1 / 2√2)Î + (√3 + 1 /2√2) J cap

Answer 1

$represents root

1)A=$(1+1)=$2

2)B=$(9+9)=$18=3$2

3)C=$(3²+1²)=$(9+1)=$10

4)D=$(3+1)=$4=2

5)E=$(2+2)=$4=2
