An Intiative by Sri Chaitanya

If N is the interaction force between block-B and block-A, then interaction force between block A and wall is

\frac{\sqrt{21}}{5} N

If N is the interaction force between block-B and block-A, then interaction force between block-A and wall is

\frac{2}{5} N

The relation between accelerations of block-A and block-B,

\frac{a_{A}}{a_{B}} = \frac{2}{5}

The relation between accelerations, of block-A and block-B is,

\frac{a_{A}}{a_{B}} = \frac{2}{\sqrt{21}}

answer is C, B.
