Question

If the resultant of two equal forces inclined to each other at 60° is 8.660 N find the component force

Answer 1

Answer:

value of force is 5

Explanation:

8.660=✓{A^2 +B^2 +2AB Cos theta }

=> (8.660)^2 = A^2 +A^2 +2 AA cos 60° ( as equal forces given )

=> 75(aprox) =3A^2 (as cos 60 is 1/2 and 2 and 2 cancelled)

=>A^2 =75/3 =25

=>A is 5
