Question

If 2 vectors 6N and 8N are act at a point at an angle of 90 with each other.Determine the magnitude and direction of the resultant by drawing a vector diagram and by analatical method.

Answer 1

Magnitude is given by.

$f \: net = \sqrt{f1 {}^{2} + f2 {}^{2} }$

$= \sqrt{6 {}^{2} + 8 {}^{2} }$

$\sqrt{100} = 10$

Hence resultant force is 10N.


Thanks

Answer 2

Since they both are perpendicular to each other ..
√6 square +8squre
I.e √100 = 10
