Three blocks with masses $\displaystyle m, 2 m$ and $\displaystyle 3 m$ are connected by strings, as shown in the figure. After an upward force $\displaystyle \mathrm{F}$ is applied on block $\displaystyle m$, the masses move upward at constant speed $\displaystyle v$. What is the net force on the block of mass $\displaystyle 2 m$ ?
($\displaystyle g$ is the acceleration due to gravity)
