Find the magnitude of the vector v j−k
WebFormula. The magnitude of a vector, v = (x,y), is given by the square root of squares of the endpoints x and y. Thus, if the two components (x, y) of the vector v is known, its magnitude can be calculated by Pythagoras … WebSep 22, 2016 · If $\vec B$ is subtracted from $\vec A$ , the result is −3.20 + 5.8j. What is the magnitude of $\vec A$? Am I supposed to subtract the two, so 8i - 4.6j? But then how would I find A's magnitude? To find magnitude, I would need to multiply direction, length, and a random choice of either sin or cos. BUt I can't do that with the data I have.
