Three blocks A, B, and C of masses 4 kg, 2 kg and 1 kg respectively, are in contact on a 14 N is applied to the 4 kg block, then the contact force between A and B is

• 2 N

• 6 N

• 8 NÂ

• 18 NÂ

B.

6 N

Given, mA = 4 kg
mB = 2 kgÂ
=> mC =1 kg

So total mass (M) Â = 4+2+1 = 7 kg
Now, F = MaÂ
14 = 7a
a=2 m/s2

F-F' = 4a
F' = 14-4x2
F' = 6N

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
