Figure shows two blocks. A rough surface are identified as shown in figure. Blocks and man are initially at rest. The man started running with non-zero acceleration on surface 'A' and jumps on surface 'C' and stays there stationary w.r.t. other block. Then –

Column I | Column II |
(i) Direction of contact force on ' A ' when man is on ' A ' | [D] |
(ii) Direction of contact force on surface B when man is on A | [B] |
(iii) Direction of contact force on surface ' C ' when man | [C] |
(iv) Direction of contact force on surface ' D ' when man reaches at ' C ' | [D] |

(i)-[C], (ii)-[A], (iii)-[D], (iv)-[B]
Sol. Contact force on a surface is given by

Where
= normal force on the surface.
= friction force on the surface.
