9. In a certain region of space, a uniform electric field has a magnitude of 4.6 x 10¹ N/C and points in the positive x direction. Find the magnitude and direction of the force this field exerts on a charge of -9.30 uc.

5. Two parallel, metal plates with separation distance d=2.00 cm carry charges of equal magnitude but opposite sign. Assume the electric field has a magnitude of 2,000 N/C. A charged particle with mass 2.00x10-16 kg and charge 1.00x106 C is projected from the center of the bottom negative plate with an initial speed of 1.00x105 m/s at an angle of 45 degrees above the horizontal. Assume the plates are square with side length 20.0 cm. a. Where does the particle strike? Answer: b. What is the minimum initial speed the particle must have in order to reach the positive plate. Answer:

The cockroach Periplaneta americana can detect a static electric field of magnitude 9.00 kN/C using their long antennae. If the excess static charge on a cockroach is modeled as point charges located at the end of each antenna, what magnitude of charge q would each antenna possess in order for each antennae to experience a force of magnitude 4.50 µN from the external electric field? Calculate q in units of nanocoulombs (nC). q = nC
