A hemisphere bowl of radius r cm is resting in a fixed position with its rim horizontal. A small marble of mass m is moving in a horizontal circle around the smooth inside of the bow. The plane of the circle is 3 cm below the plane of the rim of the bowl. Find the angular speed of the marble.

What have you tried so far?

I always found that a diagram really helped with these types of questions

2 starting points would be:
Try finding the radius of the circle that the particle traces
You should know that the reaction force R will act perpendicularly to the surface. The radius will also act perpendicularly to the tangent at this point, so R will act along the radius line.
