Match the following

$\begin{array}{|l|l|}
\hline \text { a) } \mathrm{mg} / 4<\mathrm{F}<\mathrm{mg} / 2 & \text { i) cube will move up } \\
\hline \text { b) } \mathrm{F}>\mathrm{mg} / 2 & \text { ii) cube will not exhibit motion } \\
\hline \text { c) } \mathrm{F}>\mathrm{mg} & \text { iii) cube will begin to rotate and slip at } \mathrm{A} \\
\hline \text { d) } \mathrm{F}=\mathrm{mg} / 4 & \text { iv) normal reaction effectively at a/3 from A, no motion } \\
\hline
\end{array}$

Solution:

a) matches with ii)

b) matches with iii)

c) matches with i)

d) matches with iv)
