A = 1.0 × 10-7 C/m Plastic straw 2.0 cm 6.0 cm 2013 Parson Education In In a physics experiment, a student wants to use this charged wire to accelerate a thin plastic straw. Suppose that the plastic straw, which is 6.0 cm long, is uniformly charged to 10 nC and is placed so that the closest end is 2.0 cm away from the wire, as shown. What is the total force on the plastic straw if the charge density on the wire is A = 1.0 × 10-7 C/m?
