A force of 10 N displaces an object through 20 cm and does 10 J of work in the process .Find the angle between force and displacement.

It would be appreciated if you verified the question,as to my knowledge the data is misleading.

we know that work done is given as W = FsCosθ hereF = 10N s = 20cm = 0.2 mand W = 1 J so,as Cosθ = W / FsCosθ = 1 / 0.2X10orCosθ = 1/2 thus, the angle will be, θ = 60o
Very correct.But the question says work done is 10J,isn't it?
