hernandez (ah29758) – Homework 1 – Hoffmann – (56605) 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 10.0points There are two identical small metal spheres with charges 70 . 7 μ C and - 62 . 8843 μ C. The distance between them is 2 cm. The spheres are placed in contact then set at their original distance. Calculate the magnitude of the force be- tween the two spheres at the final posi- tion. The value of the Coulomb constant is 8 . 98755 × 10 9 N · m 2 / C 2 . Answer in units of N 002 10.0points Charge Q is on the y axis a distance a from the origin and charge q is on the x axis a distance d from the origin. What is the value of d for which the x component of the force on q is the greatest? 1. d = q Q a 2 2. d = a 2 3. d = q Q 2 a 4. d = q Q a 5. d = 0 6. d = a 2 7. d = 2 a 8. d = a 9. d = q Q a 2 003(part1of2)10.0points A strong lightning bolt transfers about 22 . 06 C to Earth. How many electrons are transferred? The charge on an electron is - 1 . 602 × 10 19 C. 004(part2of2)10.0points The lightning bolt discharge lasts one mil- lisecond. What is the average current flowing from the cloud to ground? Answer in units of A 005(part1of2)10.0points Note that N/C = V/m Two charges are located on a horizontal axis. 2 . 5 μ C 2 . 5 μ C p 1 . 7 m 2 m 2 m Determine the electric field at p on a vertical axis as shown in the figure, where up is positive. The Coulomb constant is 8 . 98755 × 10 9 N
