Q1. A thin, horizontal copper rod is .989696 m long and has a mass of 43.3758 g.

The acceleration of gravity is 9.8 m/s2.

What is the minimum current in the rod that will cause it to float in a horizontal magnetic field of 1.70982 T?

Q2. A small remote-control car with a mass of 1.60 kg moves at a constant speed of v = 14.0 m/s in a vertical circle inside the hollow metal cylinder that has the radius of 5.00 m.

What is the magnitude of normal force exerted on the car by the walls of the cylinder at point A (at the bottom of vertical circle)?
