when we slip marble in smooth bowl , what will be reaction of marble.?

Answer 1

The marble rolls around.

If it should happen to roll up the side of the bowl, it will roll down again, unless it was going so fast it could escape the bowl. In that case it will escape the bowl and fall on the table, or whatever the bowl was resting on. Then it might roll on the floor. If the door is open it might roll out the door, and then the sky's the limit.

Answer 2

Marble will roll round the bowl without stop. It executes circular motion.
