A. 3.5 x 10-3 J
B. 3.5 x 104 J
C. 3.5 x 106 J
D. 3.5 x 109 J
To find the work done in raising the elevator, we can use the formula for work done against gravity:
Work=Force×Distance
Given:
Force (FFF) = 3.5×10−63.5 \times 10^{-6}3.5×10−6 N
Distance (ddd) = 1000 m
Substituting the given values:
Work=3.5×10−6N×1000m
Work=3.5×10−3J
If correct, the work done is 3.5×10−33.5 \times 10^{-3}3.5×10−3 Joules.
The correct answer to the question: "An elevator weighing 3.5 x 10-6 N is raised to a height of 1000 m in the absence of friction, the work done is_________________?" is "3.5 x 10-3 J".

Correct option is “A” not “D”
So th correct answer is 3.5 X10*-3
W=fxd
3.5×10*-10×1000=3.5×10*-3
Answer should be 3.9×10-9 bcz -6+3=-9 greater number is in negative so answer should be also In negative
Wrong … A is the correct option
As
W= F.d cos o
If the weight is 3.5 × 10^6N then given answer is correct otherwise for 3.5× 10^-6N all options are incorrect
It’s correct answer will be (a).
3.5 ×10^-3 is right answer
