Question

a pile of one rupee coins remains intact when the lowest point
in the pile is struck quickly by a knife give reason

Ankur · Accepted Answer

This happens on account of inertia of rest of the coins piled over
one another The lowermost coin under the pile of coins comes into
state of motion when it is struck by a knife and hence the pile of
coins remains intact when the lowermost coin flew away
