I want to ask the direction of normal force acting on the rod by the rim of the bowl. Is the direction perpendicular to the rod or will it be directed horizontally to the left?

My guess would be horizontally to the left because the normal force would be perpendicular to the "plane / surface" which is the tangent to circle (in this case, the tangent to the rim of bowl and the tangent will be vertical). Is this correct?

Thanks

Yes I think so too

If the rod was touching the bowl externally then the normal force would be perpendicular to the tangent at the point of contact.
