NEET · Physics · STD 11 - 6. system of particles and rotational motion
Two particles of mass \(5\, kg\) and \(10\, kg\) respectively are attached to the two ends of a rigid rod of length \(1\, m\) with negligible mass. The centre of mass of the system from the \(5\, kg\) particle is nearly at a distance of \(..........\, cm\)
- A \(80\)
- B \(33\)
- C \(50\)
- D \(67\)
Answer & Solution
Correct Answer
(D) \(67\)
Step-by-step Solution
Detailed explanation
\(mr =\) constant \(\Rightarrow r \propto \frac{1}{ m }\) \(\frac{ r _{1}}{ r _{2}}=\frac{ m _{2}}{ m _{1}}=\frac{10}{5}=\frac{2}{1}\)
