Unformatted text preview: homework 02 FAUSAK, TAYLOR Due: Jan 28 2008, 4:00 am 1 Question 1, chap 23, sect 2. part 1 of 3 10 points A uniformly charged circular arc AB of ra- dius R is shown in the figure. It covers a quarter of a circle and it is located in the sec- ond quadrant. The total charge on the arc is Q > 0. The value of the Coloumb constant is 8 . 98755 10 9 N m 2 / C 2 . x y + + + + + + + + + R x y I II III IV B A O s R What is the direction of the electric field vector vector E at the origin, due to the charge distribution? 1. along the negative x-axis 2. along the positive y-axis 3. in quadrant III 4. along the positive x-axis 5. along the negative y-axis 6. in quadrant I 7. in quadrant IV 8. in quadrant II Question 2, chap 23, sect 2. part 2 of 3 10 points Find E x , the x-component of the electric field at the origin due to the full arc length for the case, where Q = 0 . 8 C and R = 0 . 26 m. Answer in units of N / C. Question 3, chap 23, sect 2. part 3 of 3 10 points If at O we have E x = C , then what is the magnitude of the full force F (not just the x-component) on an electron at this point? 1. F = C 2 e 2. F = 2 C 3 e 3. F = C e 2 4. F = C 3 e 5. F = eC 6. F = 3 eC 2 7. F = 2 eC 8. F = 2 eC 9. F = 3 eC 10. F = 4 eC Question 4, chap 23, sect 2. part 1 of 4 10 points Consider a disk of radius 4 . 3 cm, having a uniformly distributed charge of +3 . 6 C. The value of the Coulomb constant is 8 . 98755 10 9 N m 2 / C 2 . Compute the magnitude of the electric field at a point on the axis and 3 . 8 mm from the center. Answer in units of N / C. Question 5, chap 23, sect 2. part 2 of 4 10 points It is interesting to compare this result with the exact answer from the previous question....
