    You didn't count with the weight of the table.

    Ok, well that 0.5N.will act in the downward direction on the table. And weight of the table will be 0.2 x 10 = 2N.
    Hence the total force would be 7 N. downward. On leg reaction would be 7/4 = 1.75N.
    Is it correct?

    2N force acts on the whole table because of the collisions. See your own solution in the first post.
