- Work done: It is the dot product of Force and Displacement.
\(W = \overrightarrow{F}.\overrightarrow{d}=Fd~cosθ\)
where W is the work done, F is the force, d is the displacement, and θ is the angle between F and d.
CALCULATION:
Given that W = 1J; F = 10N; d = 10cm = 0.1m;
Work done is given by
\(W = Fd~cosθ\)
\(1 = 10\times 0.1~cosθ\)
1 = cosθ
cos 0° = cosθ
θ = 0°
- So the angle between force and displacement is 0°
- Hence the correct answer is option 4.
