One is at x 1.00 m, and the other is at x 1.00 m. (a) Determine the electric field on the y axis at y 0.900 m N/C i N/C j (b) Calculate the electric force on a -3.00 HC charge placed on the y axis at 900 m. N j Submit Answer Save Progress Practice Another Version 4. -1 points SerPSET9 23. 038. A uniformly charged disk of radius 35.0 cm carries a charge density of 8.10 x 1013 c/m2. Calculate the electric field on the axis of the disk (a) 5.00 cm

Explanation / Answer

  a) E1 = (9x10^9x7x10^-6)/(1^2+0.9^2)

= 63000 / 1.81 = 23360.15 N/C

|E2| = |E1| = 23360.15 N/C

E1y = E1 sin theta = E1 (0.9 / sqrt(1.81)) = 15627.12

total = 2E1y =0i +31254.24 N/C

b) F = qEy = 3 x 10^-6 x 31254.24 =0i - 0.094 N
