Question

a force of 10 N makes angle of 60 with Y axis its component in y axis wil be with explanation answer ​

Answer 1

Force = 10N

∅ = 60°

The force makes 60° with the y-axis

So, the component of the force in y-axis will be

Fcos∅ = 10×cos60° = 10×1/2 = 5N.

There cannot be any explanation of why we do that (• ▽ •;) but, the axis with which the vector makes angle , marks the cos component of the vector(here force)
