An industrial mining process uses electrostatic forces to separate small particles of quartz from small particles of phosphate. Both particle types are preprocessed so that they are clean, dry, have diameters of approximately 2.5e-01 mm, and have charge-to-mass ratios (either positive or negative) of approximately Q/m = 1e-05 C/kg. They fall from a vibrating hopper through a constant electrostatic field of E = -1.1e+05 x V/m, generated by an applied voltage potential of V. 

Calculate the applied voltage potential, V (in Volts), needed to generate this field. What is the vertical distance (in meters) the particles will fall before this separation distance is achieved? What is the time (in seconds) required for the quartz and phosphate particles to achieve a separation distance of 1.0 m
