Question

Find a unit vector parallel to the resultant of vectors A vector= 3i-2j+4k B vector=i-4j+5k

pls dont copy and correct answer gets brainliest

Answer 1

RESULTANT VECTOR = 4i - 6j + 9k

UNIT VECTOR =

$\frac{resultant \: vector}{magnitude \: of \: resultant \: vector}$

$\frac{4} { \sqrt{133} } i - \frac{6}{ \sqrt{133} } j + \frac{9}{ \sqrt{133k} }$

Answer 2

Explanation:

RESULTANT VECTOR = 4i - 6j + 9k

UNIT VECTOR =

$\frac{resultant \: vector}{magnitude \: of \: resultant \: vector}$magnitudeofresultantvectorresultantvector

$\frac{4} { \sqrt{133} } i - \frac{6}{ \sqrt{133} } j + \frac{9}{ \sqrt{133k} }1334i−1336j+133k$
