Two block of masses `2kg` and `4kg` are released from rest over a smooth inclined place of inclination `30^(@)` as shown in figure what is the normal force between the two blocks?

Text Solution

Verified by Experts

Since surface is smooth acceleration of both is `g sin theta = 10 sin 30^(@) = 5 m//s^(2)` down the plane.
The component of `mg` down the plane `(= mg sin theta)` provides this acceleration. So normal reation will be zero.
