Question

Question-
The resultant of two forces acting at an angle of 150° is 10 N and is perpendicular to one of the forces.
The other force is?​

Answer 1

Answer:

$\huge\mathfrak\color{pink}Answer$

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°) = R =10 ⇒ A = 20N ,

⇒Asin (60°) = B ⇒ B = $10 \sqrt{3}$

THEREFORE,

Forces are 20N and$10 \sqrt{3}$
