Calculate the average value of the electric field along the straight line between the two point charges by dividing the difference in the magnitude of the voltages at the two point charges by the displacement between the two point charges. Then take the % difference between your two values for the average electric field between the two point charges. (5 points)

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
