A) 96
B) 128
C) 32
D) 64
Correct Answer: C
Solution :
\[{\frac{{{V}_{A}}}{{{t}_{A}}}}/{\frac{{{V}_{B}}}{{{t}_{B}}}}\;=\sqrt{\frac{{{M}_{B}}}{{{M}_{A}}}}\] \[\Rightarrow \]\[\frac{200}{150}=\sqrt{\frac{36}{{{M}_{A}}}}\Rightarrow \frac{4}{3}=\sqrt{\frac{36}{{{M}_{A}}}}\] \[\Rightarrow \]\[\frac{16}{9}=\frac{36}{{{M}_{A}}}\Rightarrow \frac{81}{4}=20.25\] So, most approximate answer is 32.You need to login to perform this action.
