Answer:
The two forces are acting at an angle of 120°
Step-by-step explanation:
From the figure it can be seen that
" In the parallelogram the resultant is at right angles to force 6n
The forces are acting at an angle 90° + x°
As this is parallelogram the side opposite to 6n must be equal to 6n
6n
if we take sin x = -------
12n
= 0.5
Therefore x must be equal to 30°
Therefore the two forces are acting at an angle
= 90° + 30°
= 120 °
