Charged tape A strip of invisible tape 12 cm by 2 cm is charged uniformly with a total net charge of 4 x 108 coulomb and hangs vertically. You wish to determine the electric field at a perpendicular distance of 3 cm from the center of the tape. Which of the following statements are true? (Select all that apply.) O It is better to use more, smaller pieces, because each piece is more like a point charge. O Using 3 pieces gives a more accurate result than using 8 pieces. O Using more than 8 pieces would make the calculation more accurate. O Using more than 8 pieces would not make the calculation more accurate. OUsing fewer pieces reduces the error. Using 8 pieces gives a more accurate result than using 3 pieces.
