Question

what is the numerical value of the vector 3 ICAP + 4 j cap + 5 k cap ​

Answer 1

$A^{→} = 3 i + 4j + 5k$

$\implies \: | A^{→}| = \sqrt{ {3}^{2} + {4}^{2} + {5}^{2} }$

$\implies |A^{→}| = 5 \sqrt{2} \: units$

Answer 2

Answer:

7.07

Explanation:

=3i + 4j + 5k

=$\sqrt{3^2 + 4^2 + 5^2}$

=$\sqrt{9+ 16 + 25}$

=7.07
