Question

4. A force of 5N acts on a particle along a direction making
an angle of 60' with vertical. Its vertical compone
(a) 10N
(b)3N
(C)4N
(D)2.5​

Answer 1

vertical component = F × Cos@ because angle made with vertical
= 5× cos60° = 5×1/2 = 2.5N

Answer 2

hey mate!

--------------

see brother answer is D =2.5

how??

see as it is along the vertical so we will take the component along it!!

as it is base/hypotenuse it will be

FCOS60°

GOT IT??

so i will write force 5 as it is given

so this will become, 5cos60°

and cos60° is a standard value 1/2

putting it in equation,

5/2

which gives

2.5

thanks!!

answer is in Newton;(N)
