Forces and Equilibrium : Find the force b/w the blocks?

[devvaibhav]

1. Two blocks are moved with constant velocity up the inclined plane with the help of force F as shown in the figure. Find the value of F and the force acting b/w the blocks.

Homework Equations

Nothing is given.

The Attempt at a Solution

I got the solution of the Force( F ) which is 15 N by considering the two blocks as a single system, making its F.B.D. and finding its components...The answer for F is correct. But i was unable to find the force acting b/w the blocks...Thanks. Waiting for an answer...

Make a free-body diagram for the 1 kg block. You know the component of gravity along the slope, and an other force (call it N) is exerted on it by the other block.

thnx ehild
Wt. of 1 kg block= 10N
10sin30 = N
Therefore, N= 5 N...

Thank u so much...
