Question

Supose we have a pile of three books on a table. If we try pushing the pile with all the fingers of one hand, we will be able to move the books easily. However, this will not be the case if we try pushing the pile with only the index finger.but when only one finger is used the surface area becomes less and hence the pressure exerted is more.......so we should be able 2 move it easily..........???????

Answer 1

no we can't move it easily because if we use all fingers the force exerted on it is evenly spread along the book
