A single horizontal force F is applied to a block of mass M1, which is in contact with another block of mass M2. If the surfaces are frictionless, the force between the blocks is

if u caluclte net force then it will be F as block M1 will aplly F force to M2 block and in turn M2 block will apply same amount force to block M1 so net force will be F

But the answer given is (M2F)/(M1+M2)

Looking for something else?

i only know the formula to get this ans but dunno the reason

Draw the force diagrams of each body. You will see that for the second body, N=M2a(If N is force applied by the blocks on each other and a is acceleration of the system). For first body F-N=M1a Now solve for N.

a=F/(M1+M2) We apply a force F on the first body. But the body does not apply the same force on the other body. There is a sort of loss while the body transfers our force to the other body

Why F-N=M1a?

now we will draw free body diagram |dw:1331304089665:dw| so F-N=M1a
