Question

When a fast moving carrom striker horizontally hits
at the bottom of the pile, the bottom-most coin
moves out quickly while other coins fall vertically
down on the table. The reason behind falling of other
coins on the table is
(1) Inertia of bottom-most coin
(2) Inertia of striker
(3) Inertia of table
(4) Inertia of falling coins apart from bottom-most
coin​

Answer 1

4) Inertia of falling coins apart from bottom most coin

Answer 2

'The inertia of falling coins apart from bottom-most  coin'​

Answer: Option 4

Explanation:

When a striker hits the coin with a striking speed, the inertia of striker makes the below coin to move and the rest coins to fall.

The inertia of motion states that a body continues to be in a state of rest or state of motion until an 'external force' is applied to make it move or bring it to rest.

Here too, the coins were in a state of rest and came into motion when the striker hit the coin with a speed, as a result the below coin moved away. With the movement of the last coin, the above coins fell apart as they were still in a state of rest and the last coin moved away which also was in a state of rest.
