Answer:
the weight of the objects inside the box
Explanation:
Given that a box is lifted and we have to calculate the factor which influences the amount of energy it takes.
We have energy = work done
Work done = Force x displacement
Force = mass x acceleration
Here acceleration=acceleration due to gravity and this remains constant irrespective of shape of box, weight or time of day
Thus we get
energy taken = work done
= Force x displacement
= mgh
where h = height lifted
g= acceleration due to gravity
m = mass of the box
Hence we find that II option the weight of the objects inside the box
is right.
