component will be:
A.
5.5 N
B.
8.6 N
C.
7.5 N
D.
10 N​

Answer 1

Answer:

Hi

Explanation:

Given:

A force of 10N makes an angle of 30° with y-axis. Find the magnitude of x-component?

Solution:

Since this force does make an angle of 30 ∘∘ with the y-axis we now have a 30 ∘∘ - 60 ∘−9∘−9 0 ∘∘ right triangle.

To find the x magnitude we take the sin of 30 ∘∘ ×× the force of 10N (hyp.) or sin 30 ∘∘ = x/10N ===> x = 10N ⋅⋅ sin30 ∘∘ ===> x = 5 N

Answer is: 5N

l hope it helps you ☺☺
