Correct option is A)

where, $F$ is the force applied, $s$ is the displacement, and $θ$ is the angle between the force applied and displacement

Hence, work done is independent of time taken.

In the given cases, $θ=0_{∘}$ as the force applied are in the same direction. Also, $F=mg$

So $W=Fs=mgs$

In both the cases, mass and displacement are the same.

$W=50×10×2=1000J$

$W=50×10×2=1000J$

Hence work done is in the ratio of $1000:1000=1:1$.
