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 situtation, mark out the correct statement (s).

Options

A. `N_(1)=N_(2)=N_(3)`
B. `N_(1) lt N_(2) =N_(3)`
C. `N_(1)=N_(2) lt N_(3)`
D. `N_(1)=N_(2) gt N_(3)`

Answer

C

Explanation

Let the weight of each block be W

So, `N_(1)=N_(2)=(N_3)/(2)`.
