A) \[{{30}^{o}}\]
B) \[{{45}^{o}}\]
C) \[{{60}^{o}}\]
D) \[{{90}^{o}}\]
Correct Answer: B
Solution :
Applying law of conservation of momentum along two axes of plane of motion, we get: \[{{V}_{3}}\] i.e.\[,\] \[MgC{{l}_{2}}\to 2NaOH\to Mg{{(OH)}_{2}}\downarrow +2NaCl\] ? (i) Also, \[Mg{{(OH)}_{2}}\] \[M{{g}^{2+}}\] \[O{{H}^{-}}\] \ \[{{K}_{sp}}\] According to law of conservation of KE \[Mg{{(OH)}_{2}}\]You need to login to perform this action.
