Question

Find the resultant (in components)and it's magnitude. where p=[0,1,2],q=[3,-1,4],u=[2,0,2],v=[3,-3,0]

Answer 1

magnitude :
$|012|$
$\sqrt{0 {}^{2} { + 1 {}^{2} +2 }^{2} }$
$\sqrt{0 + 1 + 4}$
$= \sqrt{5}$
like wise we have to calculate for magnitude
resultant for example for resultant value of p is

+or -
$\sqrt{5} \div 2$
likewise we have to calculate for resultant
