Question

The resultant of two concurrent forces
is 1500, and the angle b/w the forces
is 90°. The resultant makes anangle
of 36° with one of the forces. Find
the maquetude of each torce​

Answer 1

Explanation:

Let forces are A and B.

R is the resultant force of A and B. As shown in figure, R is perpendicular to the B.

From the figure, Acos(60

o

)=R=10 ⇒A=20N,

⇒ Asin(60

o

)=B ⇒B=10

N,

∴ Forces are 20N and 10
