Question

the resultant of two forces 10N and 15N acting along +x and -x is?​

Answer 1

Answer:

5 is your answer.hope it helps you

Answer 2

Answer:

5 N along negative x-axis direction.

Explanation:

Let's consider

F1 = 10 N along positive x-axis

F2 = 15  N along negative x- axis

Since , both of them are in opposite direction, so, angle between them is $180^{o}$

and Force is vector quantity so resultant force,

$F=\sqrt{(F1)^{2}+(F2)^{2}+ 2.F1.F2.cos\theta} \\\\=\sqrt{(10)^{2}+(15)^{2}+ 2.10.15.(-1)}\\\\=(\sqrt{325-300})\\\\=\sqrt{25}$

= 5 N

Hence, the resultant force will be 5 N in negative x axis direction.
