Answer 2

Answer:

the best way to recognize that is that .

the line which is attached to the angle theta would use cos theta

so in your question w is weight i.e.mg

and formula is mgcos theta or wcos theta...

F = mgcos theta

because it is the case of equilibrium

means when we will measure the value the object will be at rest for a instant ...

it's equalize the force..

hope you understand..
