Question

If initial position of a object is (-1,2,3) and final position of a object is (-2,-3,,4) the n find displacement and magnitude

Answer 1

Answer:

$( - i - 5j + k) \\ \\ \sqrt{27 \: \: \: } \: \: \: or \: \: 3 \sqrt{3} \: \: \: units$

Explanation:

$displacement \: = ( - 2i - 3j + 4k) - ( - 1i + 2j + 3k) \\ = - i - 5 j + k$

$magnitude \: = \: \sqrt{ {1}^{2} + {( - 5)}^{2} + } {1}^{2} \\ \\ = \sqrt{1 + 25 + 1 } \\ \\ \\ = \sqrt{27 } \\ \\ 3 \sqrt{3} \: \: \: \: units$
