friction
Acc to my understanding
W1 is work done by friction in moving from a to c' to b
W2 is work done by friction in moving from a to c to b
Clearly the path length acb is larger
Since friction is a non conservative force it depends upon the path length . Therefore w2>w1
Toppr site says otherwise and coaching module says w1=w2

Note for OP
+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.@Real potato any ideas?
Im out ill definitely look into this once i get bck to home
ohkk , np
W1=w2 use Work energy theorem
but friction is non conservative so it should depend on path taken, w2>w1
Vertical plane h
Har jagh normal same thodi hai
Directly friction nhi nikal sakte
Wd by frction + wd by mg = k2-k1=0
Dono hi case m A to B jara hai to work done by mg constant hai
Islie firction ka work dono case me same hoga
k2 and k1 is kinetic energy final and initial respectively ?
if yes then how do we know particle has same velocity upon reaching b through 2 diff paths
It is the difference in kinetic energy
Initial bhi velocity zero h Finally bhi zero
ohh , got it. big brain question. thanxx
can you please the "elastic rubber " one too @Real potato . thanks again
Let me see
