- We’ve seen that bees develop a positive charge as they fly through the air. When a bee lands on a flower, charge is transferred, and future bee visitors to the same flower can sense this charge and seek out a more promising bloom. Experimenters have done tests to determine the limits of bumblebee field sensitivity. In one test, bumblebees could detect, from a distance, the charge on a 3.0-cm-diameter sphere that had been charged to 30 V. What was the magnitude of the charge on the sphere?Two 2.0-mm diameter beads, C and D, are 12mm mm apart, measured between their centers. Bead C has mass 1.0 g and charge 2.5nC nC.

Healthy red blood cells are negatively charged, but unhealthy cells (due to the presence of a bacteria, for example) can become positively charged. In the figure, three red blood cells are oriented such that they are located on the corners of an equilateral triangle. The red blood cell charges are A = 1.90 pC, B = 6.50 PC, and C= -4.80 pC.
