Question

Vector B~ has x, y, and z components of 8.7,

1.4, and 6.5 units, respectively.
Calculate the magnitude of B~ .

Answer 1

The magnitude of B is
`10.95\ units`

Step-by-step explanation:

we know that

The magnitude of Vector B is

`B=\sqrt{x^(2)+y^(2)+z^(2)}`

where

x,y and z are the components of vector B

we have

`x=8.7\ units, y=1.4\ units,z=6,5\ units`

substitute

`B=\sqrt{8.7^(2)+1.4^(2)+6.5^(2)}`

`B=√(119.9)`

`B=10.95\ units`
