Q1. Runner A is at first 5.4 km west of a flagpole and is running with a constant velocity of 2.6 km/h due east. Runner B is initially 3.0 km east of the flagpole and is running with the constant velocity of 8.8 km/h due west. What would be the distance of the two runners from the flagpole while their paths cross?
Q2. Find the volume density of electric charge at x = 0.270 m. Suggestion is that apply Gauss's law to a box between x = 0.270 m and x = 0.270 m + dx.
