Vedclass · Answer

All blocks will move with same acceleration

$a=\frac{6}{4+2}=1 \mathrm{m} / \mathrm{s}^{2}$

$\mathrm{Fcos} 60^{\circ}=$ total mass $	imes \mathrm{acc}$

$\mathrm{Fcos} 60^{\circ}=(8+6+4+2) 	imes 1$

$\mathrm{F} 	imes \frac{1}{2}=20 \Rightarrow \mathrm{F}=40 \mathrm{N}$

Two blocks are in contact on a frictionless table. One has mass $m$ and the other $2\,m$. A force $F$ is applied on $2\,m$ as shown in the figure. Now the same force $F$ is applied from the right on $m$. In the two cases respectively, the ratio force of contact between the two block will be:
