Question

if the force is applied at an angle 0 then work done is ​

Answer 1

Answer:

$\huge\red{\underline{\overline{\mathbb{ληsωεя:-}}}}$

At θ=90∘ the magnitude of the component of the force in the direction of the displacement is zero so no work is done as cos(90)=0. At θ>90∘ the magnitude of the component of the force along the line of the displacement is opposite in direction to the displacement so negative work is done, cosθ<0.

Answer 2

Answer:

At θ=90∘ the magnitude of the component of the force in the direction of the displacement is zero so no work is done as cos(90)=0. At θ>90∘ the magnitude of the component of the force along the line of the displacement is opposite in direction to the displacement so negative work is done, cosθ<0.
