JEE Mains · Physics · STD 11 - 5. work,energy,power and collision
The ratio of 10.Powers of two motors is \(\frac{3 \sqrt{x}}{\sqrt{x}+1}\), that are capable of raising \(300\,kg\) water in \(5\) minutes and \(50\,kg\) water in \(2\) minutes respectively from a well of \(100\,m\) deep. The value of \(x\) will be
- A \(2\)
- B \(4\)
- C \(2.4\)
- D \(16\)
Answer & Solution
Correct Answer
(D) \(16\)
Step-by-step Solution
Detailed explanation
Average 10.Power \(=\frac{\text { total } \text { work done }}{\text { total time }}\) So,\(P=\frac{m g h}{t}\) \(\frac{P_1}{P_2}=\frac{\frac{m_1 g h}{t_1}}{\frac{m_2 g h}{t_2}}=\frac{m_1}{t_1} \frac{t_2}{m_2}\)…
