Q. A wooden box is placed on a table. The normal force on the box from the table is $N_{1}$. Now another identical box is kept on first box and the normal force on lower block due to upper block is $N_{2}$ and normal force on lower block by the table is $N_{3}$. For this situation, mark out the correct statement(s).

Laws of Motion

Solution:

Let the weight of each block be $W$ (see figure)

So, $N_{1}=N_{2}=\frac{N_{3}}{2}$
