rider stands on a scale in a Ferris wheel that is turning counter-clockwise in a vertical circle of radius

10\,\text{m}

. When the rider is at the lowest point, the scale reads

2.1\times10^{3}\,\text{N}

. Assuming negligible friction, what will the scale read when the rider reaches the highest point of the circle? (Use

g = 9.8\,\text{m}\,\text{s}^{-2}

.) (a)

5.9\times10^{2}\,\text{N}

(b)

9.2\times10^{2}\,\text{N}

(c)

0\,\text{N}

(d)

2.5\times10^{2}\,\text{N}
