size 200 mm*200 mm . weight of ball is 10 kg(98.1N) it
should point conact with table than what is the stress
acting on table and why?

Exact mathematical geometries arent followed in real world, and this is actually not a case of point contact. Rather, the ball would depress a certain amount, and a finite small surface would be in contact. For kinematic analysis, we may assume this insignificant and assume it a point contact.
