Unformatted text preview: gonzales (pag757) – Homework 2 – Hoffmann – (56745) 1 This print-out should have 20 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points A rod 6 . 1 cm long is uniformly charged and has a total charge of- 15 μ C. Determine the magnitude of the elec- tric field along the axis of the rod at a point 36 . 1231 cm from the center of the rod. The Coulomb constant is 8 . 98755 × 10 9 N · m 2 / C 2 . Answer in units of N / C. 002 10.0 points A 9 . 6 g piece of Styrofoam carries a net charge of- . 5 μ C and floats above the center of a very large horizontal sheet of plastic that has a uniform charge density on its surface. The acceleration of gravity is 9 . 8 m / s 2 and the permittivity of free space is 8 . 85419 × 10- 12 C 2 / N / m 2 . What is the charge per unit area on the plastic sheet? Answer in units of μ C / m 2 . 003 10.0 points A 82 cm diameter loop is rotated in a uniform electric field until the position of maximum electric flux is found. The flux in this position is measured to be 2 . 54 × 10 5 N · m 2 / C....
