Question

The magnitude of vector , V ⃗ =2 i ∧ +5 j ∧ −6 k ∧ V→=2i∧+5j∧−6k∧ is

Answer 1

Explanation:

$magnitude \: \: of \: \: vector \: = \sqrt{a {}^{2} + {b}^{2} + {c}^{2} }$

Here

v = 2i + 5j -6k

$|v| = \sqrt{ {2}^{2} + {5}^{2} + ( { - 6}^{2} ) } \\ \\ = \sqrt{4 + 25 + 36} \\ \\ \sqrt{65 } \: \: unit$
