A thin circular sheet of glass of diameter 6 meters is rubbed with a cloth on one surface, and becomes charged uniformly. A chloride ion (a chlorine atom which has gained one extra electron) passes near the glass sheet. When the chloride ion is near the center of the sheet, at a location 0.5 mm from the sheet, it experiences an electric force of 4e-15 N, toward the glass sheet. In this problem, use the value e0 = 8.85e-12 C2/(N·m2)
It will be useful to you to draw a diagram on paper, showing field vectors, force vectors, and charges, before answering the following questions about this situation.
A.) How much charge is on the surface of the glass disk? (give amount, including sign, and correct units)
According to legend, to determine whether the king's crown was made of pure gold, Archimedes measured the crown's volume by find out how much water it displaced. The density of gold is 19.3g/cm^3. If the crown's mass was 6.00 * 10^2g, what volume ..
