Which of these statements are/is correct
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:
A block of mass $m_1=1 \ kg$ another mass $m_2=2 \ kg$, are placed together (see figure) on an inclined plane with angle of inclination $\theta$. Various values of $\theta$ are given in List $I$. The coefficient of friction between the block $m _1$ and the plane is always zero. The coefficient of static and dynamic friction between the block $m _2$ and the plane are equal to $\mu=0.3$. In List $II$ expression for the friction on block $m _2$ given. Match the correct expression of the friction in List $II$ with the angles given in List $I$, and choose the correct option. The acceleration due to gravity is denoted by $g$.
