Question
In the arrangement show in figure all surface are smooth. Select the correct alternative (s)
Options
A.For any value of θ acceleration of A and B are equal
B.contact force between the two blocks is zero if 
= tan θ
= tan θC.contact force between the two is zero for any value of mA or mB
D.normal reaction exerted by the wedge on the block are equal
Solution
Acceleration of A g sin θ down the plane
Acceleration of B g sin θ down the plane
And also the contact force between two is zero.
Acceleration of B g sin θ down the plane
And also the contact force between two is zero.
