JEE Mains · Physics · STD 11 - 4.1 newtons laws of motion
A light unstretchable string passing over a smooth light pulley connects two blocks of masses \(m_1\) and \(m_2\). If the acceleration of the system is \(\frac{g}{8}\), then the ratio of the masses \(\frac{\mathrm{m}_2}{\mathrm{~m}_1}\) is _______.
- A \(9: 7\)
- B \(4: 3\)
- C \(5: 3\)
- D \(8: 1\)
Answer & Solution
Correct Answer
(A) \(9: 7\)
Step-by-step Solution
Detailed explanation
\(a_{5 y s}=\left(\frac{m_2-m_1}{m_1+m_2}\right) g=\frac{g}{8}\) \(\Rightarrow \frac{m_2}{m_1}=\frac{9}{7}\)
