In children's park using the part ride the visitors can be made to rotate in a vertical circle. At the top of the circle, a rider has an effective weight of magnitude `1000N`. If his actual weight is `500N` then what is the effective at eh bottom of the circle?

In a children's park, using the park ride the visitors can be made to rotate in a vertical circle. At the top of the circle a rider has an effective weight of magnitude 1000 N. If his actual weight is 500 N (i) What is his effective weight at the bottom of the cricle ? (ii) What is the effective weight when the rider is halfway to the centre of the circle ?
