the min. value of µ b/w the two blocks for no slipping is a) F/mg b) F/3mg c) 2F/3mg d) 4f/3mg
hi , in this question poin to consider is that , block 2m is not involed in any type of motion, it wil remain unmoved . so for no slipping block m should also be at rest consider block m, net force on it should be zero, T - μmg = 0 T = F ,so μ = F /mg , it will be its min. value (a)
hi ,
in this question poin to consider is that , block 2m is not involed in any type of motion, it wil remain unmoved . so for no slipping block m should also be at rest
consider block m,
net force on it should be zero,
T - μmg = 0
T = F ,so
μ = F /mg , it will be its min. value (a)
no! ans is not correct!
Hi, Sorry for that, actually I didn't consider the other block if see in the fig , the max accelaration of the combined system of both block = F/3m now we hav to find the u for this condition total horz. force on the block 2 => umg - F =m*F/3m =F/3 =>umg = 4F/3 =>u(min.)=4F/3mg minimum u value ensure no slipping at all, maens that the both block will move together for that given value of FORCE I really appreciate ur move bcz of which i cud correct my mistake ENJOY the solution
Hi,

now we hav to find the u for this condition
total horz. force on the block 2 => umg - F =m*F/3m =F/3
=>umg = 4F/3
=>u(min.)=4F/3mg
minimum u value ensure no slipping at all, maens that the both block will move together for that given value of FORCE
I really appreciate ur move bcz of which i cud correct my mistake
