Dear student

A – 3

S – 4

I – 2

N – 2

T – 1

O – 1

to select 4 letters

First u have to select the four letters and then to arrange it.
1 – two letter same two different
2 – 3 letter same 1 diff.
3 – all 4 letter same
4 – two letter of same group another of same
5 – all 4 letter diff.

after that add all the cases

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
