A) \[\frac{{{v}_{1}}-{{v}_{2}}}{k-1}\]
B) \[\frac{k{{v}_{1}}-{{v}_{2}}}{k-1}\]
C) \[\frac{k{{v}_{2}}-{{v}_{1}}}{k-1}\]
D) \[\frac{{{v}_{2}}-{{v}_{1}}}{k-1}\]
Correct Answer: B
Solution :
[b] By using \[\Rightarrow h\left( {{v}_{1}}-{{v}_{0}} \right)={{K}_{1}}\] ....(i) \[\text{And }h\left( {{v}_{2}}-{{v}_{0}} \right)={{K}_{2}}\] ....(ii) \[\Rightarrow \frac{{{v}_{1}}-{{v}_{0}}}{{{v}_{2}}-{{v}_{0}}}=\frac{{{K}_{1}}}{{{K}_{2}}}=\frac{1}{K'}\] \[\text{Hence }{{v}_{0}}=\frac{k{{v}_{1}}-{{v}_{2}}}{K-1}.\]
