1answer 2 d first question is mg(1-k)/(M + 2m).....
answer 2 d 2nd one is tat wen d force is applied 2 block1 , block 2 is unaware about it...hence both d blocks slide 2gthr and fall on d ground....
these are a few stunning questions.Try to solve these guys.Its really gives he brain a hard workout.
1)
Consider the diagram above.The two small blocks are of equal masses 'm'.The coefficeient of friction between the two blocks of masses 'm'.and the block 3 is 'k'.With what acceleration the block 3 should move towards the right to keep the blocks of masses m at rest w.r.t 3?
2)
In the picture above there is no force of friction between the incline and block 1 and also between block 1 and 2.A force F is applied on block 1.What will happen to block 2?
