A) \[\frac{2}{3}\,m{{s}^{-2}}\]
B) \[-\frac{2}{3}\,m{{s}^{-2}}\]
C) \[\frac{20}{3}\,m{{s}^{-2}}\]
D) \[-\frac{20}{3}\,m{{s}^{-2}}\]
Correct Answer: D
Solution :
Slope of line \[A{{l}_{2}}{{S}_{3}}+6{{H}_{2}}O\xrightarrow{\,}\,2Al{{(OH)}_{3}}+3{{H}_{2}}S\] Equation of line is \[M{{g}^{2+}}\] \[A{{l}^{3+}}\] \[=2\times 4=8\] Velocity of \[\therefore \] m. i.e.. \[=\frac{1}{8}\times 100\] Differentiating Eq. (i) w.r.t. time, Acceleration \[AlC{{l}_{3}}\] \[HCl\] \[AlC{{l}_{3}}+3{{H}_{2}}O\xrightarrow{\,}\,Al{{(OH)}_{3}}+3HCl\]
