Question

in the image below, where is the area of maximum stream velocity?
point c (close to the inner bank)
point a (close to the outer bank)
stream velocity is equal at this location.
point b (middle of the stream)

Explanation:

In a river, the maximum stream velocity is typically in the middle of the stream. This is because the friction with the banks and the riverbed slows down the water near the banks (like at Point A and Point C). In the middle (Point B), there is less friction from the sides and the bottom (compared to near - bank areas), allowing the water to flow faster.

Answer:

Point B (middle of the stream)
