Q1. An automobile with a mass of 1340 kg has 3.00 m between the front and rear axles. Its center of gravity is located 1.78 m behind the front axle. The automobile is on level ground.

(a) Determine magnitude of the force from the ground on each front wheel (assuming equal forces on the front wheels).

(b) Determine magnitude of the force from the ground on each rear wheel (assuming equal forces on the rear wheels).

Q2. A point charge of 9.00 ×10C is located at the origin of a coordinate system. A positive charge of 3.00 ×10-9C is brought in from infinity to a point such that the electrical potential energy associated with the two charges is 8.09 ×10-7J.How far apart are the charges at this time? Electric field, does the corresponding electric potential at the electron's changing locations increase or decrease? What about an electrical potential energy?

Q3. A duck flying due east passes over Atlanta, where the magnetic field of the Earth is 5.2 X 10^-5 T directed north. The duck has a positive charge of 4.0 X 10^-8 C. If magnetic force acting on the duck is 3.20 X 10^-11 N upward, what is magnitude of the duck's velocity? Reply in units of m/s.
