Q. A perfect smooth sphere $A$ of mass $2 k g$ is in contact with a rectangular block $B$ of mass $4 k g$ and vertical wall as shown in the figure. All the surfaces are smooth. Find the normal reaction (in $N$ ) by the vertical wall on sphere $A$ .

From FBD of system "sphere $+$ block", $\frac{N}{60} = \frac{3}{4}$
$N = 45 N$
