Question

Two vectors are given as r =2i + 3j + 5k and F=3i-2j + 4k find the resultant vector ī =r x F

Answer 1

Explanation:

here's ur answer hope this helps u..

Answer 2

$| \frac{i}{ \frac{2}{3} } \frac{j}{ \frac{3}{ - 2} } \frac{k}{ \frac{5}{4} } |$

now use determinants

i (3x4)-(5x-2) - j (2x4)-(5x3) + k(2x-2)-(3x3)

i (22) - j (-7) + k (-13)

So resulting vector is 22i + 7j - 13 k
