In \(\triangle P Q R, M\) is the mid-point of \(Q R\) and \(C\) is the mid-point of \(P M\). If \(Q C\) when extended meets \(P R\) at \(N\), then \(\frac{|\overrightarrow{Q N}|}{|\overline{C N}|}=\)
- A 1
- B 2
- C 3
- D 4
Answer & Solution
Correct Answer
(D) 4
Step-by-step Solution
Detailed explanation
We have, \(M\) is the mid-point of \(Q R\). \(C\) is the mid-point of \(P M\). Draw \(M O\) such that \(M O\) is parallel to \(C N\). \(\because N\) is the mid-point of \(P O\) \[ \therefore \quad C N=\frac{1}{2} M O \] \(M\) is the mid-point of \(Q R\) \(\therefore M O\) is…
