A solid block of mass $$3\,\text{kg}$$ is suspended from the bottom of a $$5\,\text{kg}$$ block with the help of a rope AB of mass $$2\,\text{kg}$$ as shown in the figure. When pulled by an upward force $$F$$, the whole system experiences an upward acceleration $$2.19\,\text{m s}^{-2}$$. Choose the correct option

A

Net force on the rope AB is $$24\,\text{N}$$

B

Tension at the midpoint of the rope AB is $$48\,\text{N}$$

C

Force $$F$$ is $$20\,\text{N}$$

D

Force $$F$$ is $$60\,\text{N}$$
