A 4.00 m long thin plastic rod lies on the x-axis as shown in the image below. It is centered at x = 0 and carries a uniform charge of -300 nC. A thin disk with a 6.00 cm radius is centered at (5, 10, 0) cm and has a uniform charge of 20 nC. (a) Calculate exactly the electric field Ę at the point (0, 10, 0) cm. (b) Calculate the electric field E at the point (0, 10, 0) cm using only approximations. Note: You do NOT need to solve any integrals for this problem! rod y N disk x
