In this lab you will use Excel to plot a distance x on the vertical axis and the inverse of mass m on the horizontal axis. That is, a plot of x versus 1 m . Plotted this way, the data falls on a straight line. If x is in centimeters and m is in grams, what are the units of the slope of the line? cm/g cm · g g/cm (cm · g)−1

The two metal spheres in the figure are connected by a metal wire with w switch in the middle. initially the switch is open. sphere 1, with the larger radius, i'd given a positive charge. sphere 2, with the smaller radius, is neutral. then the switch is closed. afterward, sphere 1 has charge q1, is at potential v1 and the electric field strength at its surface is e1. the values for sphere 2 are q2, v2, and e2. a. is v1 < ,> , or = to v2? explain. b. is q2 < , > , or = explain? c. is e1 < ,> ,or = to e2? explain?
