Hi!!!
Hope you are doing well.
The resultant of these two forces is given as
F1=F2=10 dynes.
Angle between F1&F2 = (180-60) = 120.
Resultant F:
Mod(F) = square root(F1^2+F2^2+2F1F2cos 120)
= square root(10^2+10^2+2(10)(10)(-0.5))
= 10
Therefore, the resultant force has also the magnitude of 10 dynes.
Hope you are clear now. Feel free to ask if you have any other queries. All The Best!!!
