Question 8: Motion in 2D & Vectors

Question

The resultant of two forces acting at an angle of 120$$^\circ$$ is 10 kg-W and is perpendicular to one of the forces. That force is

Accepted Answer

From the diagram we get,
$$	an 30^\circ  = {1 \over {\sqrt 3 }} = {x \over {10}}$$
$$ \Rightarrow x = {{10} \over {\sqrt 3 }}$$

Answer

$$\frac{10}{\sqrt3}$$ kg-W

Answer

$$10$$ kg-W

Answer

$$20\sqrt3$$ kg-W
