A block A of mass m1 rests on a horizontal table. A light string connected to it passes over a frictionless pulley at the edge of theÂ table and from its other end, another block B of mass m2 is suspended. The coefficient of kinetic friction between the block and the table isÂ .Â When the block A is sliding on the table, the tension in the string is

C.

FBD of block A,

T -m1a =Â fk ..... (i)
FBD Â of block B

m2g -T = m2a ... (ii)
Adding Eqs. (i) and (ii), we get
m2g-m1a = m2a +fk

FBD of block A,

T -m1a =Â fk ..... (i)
FBD Â of block B

m2g -T = m2a ... (ii)
Adding Eqs. (i) and (ii), we get
m2g-m1a = m2a +fk

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
