the resultant of two forces when they act at right angle is 10n whereas when they act at an angle of 60 the resultant is 146 determine magnitude of two forces
ACT Exam: Preparation Tips
Hello,
You can apply the Parallelogram Law of Vector Addition to proceed towards solution for your query.
------- The law states " if we place two vectors so they have the same initial point, and then complete the vectors into a parallelogram, then the sum of the vectors is the directed diagonal that starts at the same point as the vectors."
------- Suppose the Forces acting be F1 and F2, so going the initial statement -
Resultant, R= 10 = √( F1^ 2 + F2^ 2). ---- (i)
Also from the next statement -
146 = √ ( F1^ 2 + F2^ 2 + 2 F1 F2 Cos 60) ------ (ii)
On Solving the two equations you will get solution to your query.
Thank you.
