A) 28mm
B) 56mm
C) 70mm
D) 140mm
Correct Answer: D
Solution :
\[p=p_{A}^{\text{o}}{{x}_{A}}+p_{B}^{\text{o}}{{x}_{B}}\] \[\Rightarrow \] \[84=70\times 0.8+p_{B}^{\text{o}}\times 0.2\] \[84=56+p_{B}^{o}\,\times 0.2\] \[p_{B}^{\text{o}}=\frac{28}{0.2}=140\,\,mm\]You need to login to perform this action.
