A. work done in rolling is more than in lifting
B. work done in lifting the stone is equal to rolling it
C. work done in both is same but the rate of doing work is less in rolling
D. work done in rolling a stone is less than in lifting it

IF You Select Anyone Option Then explain How do you Prove that one option is correct✅✔​

Answer 1

Answer:

It's D

Explanation:

because you need more force to lift it rather than rolling it......and also lifting it will be difficult

Answer 2

Answer:

D. work done in rolling a stone is less than in lifting it

Explanation:

work done is the scalar product of displacement and force.

since, displacement is same, therefore work is dependent on the magnetude of force

It is given that force used in rolling is less than lifting
