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$1:2$
- Bsame
- C$2:1$
- D$1:3$
