A sphere of brass released in a long liquid column attains a terminal speed $$v0$$. If the terminal speed is attained by a sphere of marble of the same radius and released in the same liquid is $$nv0$$ then the value of n will be (Given$$: The specific gravities of brass, marble and liquid are $$8.5$$, $$2.5$$ and $$0.8$$ $$respectively)

Question
