Question

Find the magnitude vector 4ỉ + 5j+vsk​

Answer 1

Answer: √42

Explanation:

To find the magnitude, you have to calculate the square root of the squares of their sum I. E ... You just need to look at the calculation below

√ (4) ^2 + (5) ^2 + (1) ^2

= √ 16 + 25 + 1

=√ 42

But in some places they might ask you to calculate it's root as well so you have to do that.. Like you must have studied in the lower classes, right?

Hope it helps....

If it does, don't forget to mark me as the brainliest! :)

Answer 2

Explanation:

1.its simple square the two components along x and y and  z axes

2.add them

3.take square  root of the sum that's it

i did not understand the component along z axis

for convenience i took it as √8

now on squaring all the terms u get

16+ 25 +8= 49

so now taking square root  we get (7) this is how u find the magnitude

following this process u  can find magnitude of any vector

hope that  it helps you :)
