A small block with mass 0.0450kg slides in a vertical circle of radius 0.600m on the inside of a circular track. During one of the revolutions of the block, when the block is at the bottom of its path, point A, the magnitude of the normal force exerted on the block by the track has magnitude 3.85N.
