Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 2) 10.0 points A cylindrical shell of radius 10 cm and length 247 cm has its charge density uniformly dis- tributed on its surface. The electric field intensity at a point 29 . 7 cm radially outward from its axis (measured from the midpoint of the shell ) is 44200 N / C. Given: k e = 8 . 99 × 10 9 N · m 2 / C 2 . What is the net charge on the shell? Answer in units of C. 002 (part 2 of 2) 10.0 points What is the electric field at a point 4 . 6 cm from the axis? Answer in units of N / C. 003 10.0 points The nucleus of “Lead-208”, 208 82 Pb, has 82 pro- tons within a sphere of radius 6 . 34 × 10- 15 m. Each electric charge has a value of 1 . 60218 × 10- 19 C. The Coulomb constant is 8 . 98755 × 10 9 N · m 2 / C 2 ....
