First of all consider the forces on the blocks,

For the 1st block,

mg - T1 = m x a Â  Â  Â  Â ... (i)

Let us consider second and third block as a system,

Then,

T1 -Â Â = 2m x a
mg () = 3m x a

When the branches of an apple tree are shaken, the apples fall down. Why?

The apple fall from an apple tree when it shaken because of inertia of rest. Apple is in a state of rest and when the tree is suddenly shaken, apples still tends to remain in it's same state of rest whereas branches move.Â

So, the apples fall down.Â
