For a disk of radius R = 35 cm and Q = 3 ✕ 10−6 C, calculate the electric field 3 mm from the center of the disk using all three equations. (Enter the magnitude.) Efirst = N/C Esecond = N/C Ethird = N/C How good are the approximate equations at this distance? Both the second and third values are within 5% of the first, most accurate value.The second value is within 5% of the first, most accurate value. The third...
