You (mass 85 kg) are driving down a road when you approach a large dip in the road. The dip is like a part of a circle with a radius of 30m and as you go through the dip, it is like you are moving in a circle at a constant speed. When you go down into the dip you feel heavier right at the bottom, such that if you were sitting on a scale it would read more than your weight. If you are traveling at 12 m/s when you go into the dip, what would be the reading on the scale

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
