A) \[\frac{P}{Q}=\frac{2R}{{{S}_{1}}+{{S}_{2}}}\]
B) \[\frac{P}{Q}=\frac{R\left( {{S}_{1}}+{{S}_{2}} \right)}{{{S}_{1}}{{S}_{2}}}\]
C) \[\frac{P}{Q}=\frac{R\left( {{S}_{1}}+{{S}_{2}} \right)}{2{{S}_{1}}{{S}_{2}}}\]
D) \[\frac{P}{Q}=\frac{R}{{{S}_{1}}+{{S}_{2}}}\]
Correct Answer: B
Solution :
[b] \[\frac{P}{Q}=\frac{R}{S}\text{ where }S=\frac{{{S}_{1}}{{S}_{2}}}{{{S}_{1}}+{{S}_{2}}}\]You need to login to perform this action.
