Two blocks are in contact on a frictionless table. One has mass \( \mathrm{m} \) and the other \( 2 \mathrm{~m} \). A force \( \mathrm{F} \) is applied on \( 2 \mathrm{~m} \) as shown in the figure. Now the same force \( \mathrm{F} \) is applied from the right on \( \mathrm{m} \). In the two cases respectively, the ratio of force of contact between the two blocks will be:
(A) same
(B) \( 1: 2 \)
(C) \( 2: 1 \)
(D) \( 1: 3 \)
