Water is flowing steadily in a river. A and B are the two layers of water at heights 40 cm and 90 cm from the bottom. The velocity of the layer A is \(12 \mathrm{~cm} / \mathrm{s}\). The velocity of the layer B is
- A \(15 \mathrm{~cm} / \mathrm{s}\)
- B \(21 \mathrm{~cm} / \mathrm{s}\)
- C \(27 \mathrm{~cm} / \mathrm{s}\)
- D \(36 \mathrm{~cm} / \mathrm{s}\)
Answer & Solution
Correct Answer
(C) \(27 \mathrm{~cm} / \mathrm{s}\)
Step-by-step Solution
Detailed explanation
\( \frac{v_A}{h_A} = \frac{v_B}{h_B} \) \( v_B = v_A \left( \frac{h_B}{h_A} \right) \)
