A uniform electric field between two metal plates points downwards and has a strength of 4.6 x 104 N/C. What force would a 3.2 x 10-5 C charge experience if it
were placed in that field? Show your work using the GUESS method.

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
