Answer- The above question is from the chapter 'Motion in a Plane'.

Concept used: Resolution of vectors- It is a process of splitting a vector into two components i.e. horizontal component and vertical component.

Horizontal component (aₓ) = a cos θ

Vertical component (  a_{y} ) = a sin θ

Given question: Force of 10 N acts at an angle of 30° with horizontal, then it's rectangular components are ______ and ______​ .

Answer: Let the force by represented by  \vec{F} .

 \vec{F} = 10 N

θ = 30°

Vertical component (  F_{y} ) = F sin θ

Vertical component (  F_{y} ) = 10 × sin 30°

Vertical component (  F_{y} ) = 10 ×  \frac{1}{2}

Vertical component (  F_{y} ) = 5 N

Horizontal component (  F_{x} ) = F cos θ

Horizontal component (  F_{x} ) = 10 × cos 30°

Horizontal component (  F_{x} ) = 10 ×  \frac{\sqrt{3}}{2}

Horizontal component (  F_{x} ) = 5√3 N

∴ Force of 10 N acts at an angle of 30° with horizontal, then it's rectangular components are 5 N and 5√3 N.

\vec{F}

F

= 10 N

θ = 30°

Vertical component ( F_{y}F

y

) = F sin θ

Vertical component ( F_{y}F

1

Vertical component ( F_{y}F

y

) = 5 N

Horizontal component ( F_{x}F

x

) = F cos θ

Horizontal component ( F_{x}F

x

) = 10 × cos 30°

Horizontal component ( F_{x}F
