Question
In the figure show if friction coefficient of block 1kg and 2kg with inclined plane is μ1 = 0.5 and μ2 = 0.4 respectively, then
Options
A.both block will move together
B.both block will move separately
C.there is a non zero contact force between two blocks
D.None of these
Solution
a2 = 
=
= 5√3 - 2
a1 =
= 5√3 - 2.5 ; a1 < a2
OR
As μ2 < μ1 so block will move separately
=
= 5√3 - 2a1 =
= 5√3 - 2.5 ; a1 < a2
OR
As μ2 < μ1 so block will move separately
