Question

Given 2 vectors `A = 4.00i + 3.00j` and `B =5.00i - 2.00 j` how do you find the magnitude of each vector?

Answer 1

magnitude of vec `A=5`
and magnitude of vec `B =5.385`

Explanation:

Magnitude of a vector is determined by `sqrt(a^2+b^2+c^2...`
so,

`|vec A|= sqrt(4^2+3^2 = 5`

and

`|vec B| = sqrt{5^2-(-2)^2} = 5.385`
