Answer :
490 N is the magnitude of the centripetal force of rider at the top of the circle.
Describe magnitude?
Simply said, "distance or amount" is the definition of magnitude. In terms of motion, it shows the absolute or relative size, direction, or movement of an item. It is used to describe something's size or scope. Magnitude in physics often refers to a size or amount.
If the rider weighs 50 kg, then the centripetal force needed to keep him or her moving in a circle must be equal to that weight,
or
Fc=mg=509.8
N=490 N.
Describe the motion?
