Question

please answer fast please please please​

Answer 1

Three forces are of magnitude 6 N , 6 N and √72 N .

Magnitude of the resultant will be :

$\sqrt{6^2+6^2+72}\\\\\implies \sqrt{36+36+72}\\\\\implies \sqrt{144}\\\\\implies 12$

So the magnitude of the resultant will be 12 N .

The direction of the resultant will be towards OE .
