2 books of 1 Kg each are placed on a table. The coefficient of static friction between the books and the book and the table is µ. Find the minimum force F applied to the lower book so that there occurs slip between both the books.

Answer 1

Dear Student,


$$\begin{gathered} lettheforcebeF \\ thenaccnofthesystem \\ a=\frac{F-\mu \left(2g\right)}{2} \\ pseudoforceonupperbook=a \\ a=\mu g \\ \frac{F-\mu \left(2g\right)}{2}=\mu g \\ F=4\mu g \\ Regards \end{gathered}$$
