1)An object with negative charge is placed in a region of space where the electric field lines is directed vertically upward. What is the direction of the electric force exerted on this charge?

2. A free electron and a free proton are released in identical electric fields. How do the magnitudes of the electric force exerted on the two particles compare?

3) A water droplet of mass 3.00 * 10- 12 kg is located in the air near the ground during a stormy day. An atmospheric electric field of magnitude 6.00 * 103 N/C points vertically downward in the vicinity of the water droplet. The droplet remains suspended at rest in the air. What is the electric charge on the droplet?

4)Three point charges lie along the x axis. The positive charge q1=15.0 µC is at x = 2.00 m, the positive charge q2= 6.00 µC is at the origin, and the net force acting on q3 is zero. What is the x coordinate of q3?

5)Consider two electric dipoles in empty space. Each dipole has zero net charge. (a) Does an electric force exist between the dipoles; that is, can two objects with zero net charge exert electric forces on each other? (b) If so, is the force one of attraction or of repulsion?
