basic- friction work done
okay this is a pretty basic q. idk abt the sign given in the ans tho... like i was gettin work done as -1J so x = +1 (since work done is -x), but my frds were saying that they were getting x = -1. i dont see it (ig friction rusty ho gaya)
so can u guys confirm

+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Basically ye friction ne jo work Kiya hai vo puch rha hai
Aa to mera bhi 1 hi rha hai
ðŸ˜
No slipping so same acceleration hojayega and since the force and displacement are in same direction so work is +ve and question me -xJ pucha hai
So that would be why -(-1J)
@iTeachChem is it so?
yea this was my logic.
didnt check the math, just the sign, yea
okay. since there's no slipping won't friction act in the forward direcn on the lower block and backward on the upper block
meko lag rha he it shd be this but wtv idk
ur right, its option A
yeah thankss
oh lol they got it corrected too
