Shown in the figure below is a charged block on a spring of constant k = 198 Newtons/meter, under two different conditions. Initially there is no electric field and the block is located such that the spring is at its rest length. When an electric field of strength = 346 Newtons/Coulomb is applied the spring is seen to stretch a distance d = 0.16 meters. www. k mine F d Which polarity is the charge on the block?

#2: A 0.050-kg cart has a spherical dome that is charged to +1.0 x 10- C. The cart is at the top of a 2.0-m-long inclined plane that makes a 30° angle with the horizontal. The cart and the plane are placed in an upward-pointing vertical uniform 4000-N/C E field. How long will it take the cart to reach the bottom of the plane? What assumptions did you make?
Long highway tunnels must have air cleaners to remove dust and soot coming from passing cars and trucks. In one type, known as an electrostatic precipitator, air passes between two oppositely charged metal plates, as shown. The large electric field between the plates ionizes dust and soot particles, which then feel a force due to the field. This force causes the charged particles to move toward and stick to one or the other plate, removing them from the air. A typical unit has dimensions and charges asshown. What is the electric field between the plates?
