There are two blocks A and B in contact with vertical and horizontal smooth surface respectively Acceleration of A and B are `a_a and a_B` respectively along their constrained direction of motions. Relation between `a_A and a_B` is (Assume sin `23^(0) =2/5` )

A

If N is the interaction force between block-B and block-A, then interaction force between block A and wall is `sqrt(21)/s`N

B

If N is the interaction force between block-B and block-A, then interaction force between block-A and wall is `2/5` N The relation between accelerations of

C

block-A and block-B, `a_A/a_B =2/5`

D
