Hi friends,
I have an issue in solving a Collision Problem.

The problem is as:

So friends according to me the answer should be option (A) but according to question option, (B) is correct. Please try to help me in this.
I will appreciate the help.

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.
