Question

two poles A and B have radius in the ratio 1 ratio 2 what will be the ratio of their terminal velocity in the liquid​

Answer 1

Answer:

As you know the equation of continuity states:

A1v1 = A2v2

This further implies velocity is inversely proportional to area.

Now area of each ball is πr^2 aand let the radii of the balls be r1 and r2.

Next this implies velocity is inversely proportional to the square of the radius.

So you get v1/v2 = r2^2/r1^2

So I presume the answer should be 4: 1.
