Question

the vector that must be added to the vector ICAP - J cap + 2 k cap and 3 ICAP + 6 J cap - 7 k cap so that the resultant vector in a unit vector along the x axis is ​

Answer 1

Answer:

addition of two vectors

(i-j+2k)+(3i+6j-7k)

4i+5j-5k

Explanation:

magnitude=

$\sqrt{4 {}^{2} + 5 ^{2} } + 5 {}^{2}$

=

$\sqrt{46}$

since

unit vector=(4i+5j-5k)÷

$\sqrt{46}$
